11 sales promotions to boost demand

A sales promotion is more than just a discount—it’s a way to influence customer behaviour.

Imagine a restaurant offering “Buy one side, get a second free.” That simple incentive can turn a single dish into a full meal, introduce customers to new favourites, and encourage repeat purchases. Or think of a supermarket running a flash sale across selected categories: customers stock up, try new products, and return for more.

Promotions like these help businesses drive immediate sales, increase order size, and remain front of mind with customers.

When used strategically, sales promotions can do more than boost short-term revenue. They help you tackle real business challenges: moving stock, attracting new customers, and driving repeat sales.

Here are some of the key ways promotions can support your business:

• Drive short-term sales: Limited-time offers encourage customers to act quickly, increasing purchases and introducing them to new products.

  
  

• Move stock efficiently: Targeted promotions help highlight specific items or clear excess inventory, reducing storage costs.

  
  

• Attract new customers: Deals and discounts are a reliable way to win new business. A Salsify survey found that 70% of customers have made an unplanned purchase after finding a discount, showing that even small savings can spark curiosity and prompt action.

  
  

• Strengthen customer loyalty: Regular promotions give people a reason to return. In a Khoros study, 53% of customers said discounts influence their brand loyalty.

  
  

• Increase visibility: Promotions help your business get noticed and stand out, making it easier for customers to find and choose you.

  
  

• Stand out from competitors: A well-timed promotion can position your business as the clear choice in crowded markets.

  
  

• Boost average order value: Promotions create opportunities for cross-selling and upselling, encouraging customers to buy more.

  
  

• Revive interest in products: There’s a reason McDonald’s has retired and brought back the McRib dozens of times over the years, and why Oreo recently brought back its much-loved “S’moreo” flavour for a limited run. Limited-time offers can reignite interest in older or special items, sparking excitement and sales.

  
  

• Experiment and learn: Promotions reveal what motivates customers, so you can adjust your products, pricing, and offers for better results.

Looking for simple ways to boost sales and encourage customers to return? The key is to choose promotions that align with your objectives and suit the way your customers shop.

Here are 11 types of promotions you can try out across different channels. While these strategies are effective across various industries, they’re particularly beneficial for restaurants, retail businesses, and grocery stores. Many of these offers can be launched directly through Uber Eats in-app marketing tools, and they’ve been shown to increase orders by 23% and sales by 15%.

A BOGO promotion allows customers to buy one item and get another free or at a discount. You can be creative with the structure—try “Buy X, get X free” or “Buy X, get a discounted item” to suit your menu, product range, or stock objectives.

Many businesses use BOGO offers to encourage customers to try new items, shop during quieter periods, or buy more than they usually would.

For example, a sandwich shop might offer a “buy 1 sandwich, get 1 free” deal from 2–5pm to increase footfall during the lull between lunch and dinner. Or a makeup retailer could offer a free lipstick sample with a regular purchase, encouraging customers to try the product and come back for more.

You can run BOGO promotions across multiple channels—through your website, in-store, and on delivery apps—to create a consistent brand experience for customers.

On Uber Eats, it’s easy to set up BOGO offers through the Marketing tab in your Uber Eats Manager dashboard.

Bundling, or “bundle and save” promotions, group products or services together at a reduced price compared with buying each item separately. This strategy encourages customers to purchase more by highlighting the value and convenience of buying a set of complementary items.

For example, a restaurant might offer a meal bundle that includes a main, side, and a drink at a discounted price, while a supermarket could bundle pasta, sauce, and cheese. Offers like these can increase basket size by making it easier and more appealing for customers to add extra items to their purchase.

Coupons have existed for over a century—Coca-Cola is credited with distributing the first in the US around 1887, eventually redeeming 8.5 million by 1913.

Today, most customers prefer a digital version: in a recent study, 57% of consumers said they favour digital coupons over physical ones. Digital coupons work just like traditional ones, offering a barcode or promo code that customers can redeem for discounts, free delivery, or other perks. For example, new customers might receive a code such as “FIRSTTIMER” via email to save on their first delivery order.

Coupons are a powerful tool for brands across industries. They can help attract new customers and encourage repeat business if you offer them frequently enough.

For example, Walgreens uses digital coupons to drive engagement. Customers sign in to their online account to browse available coupons, inspiring new and repeat purchases.

Delivery fees can sometimes make customers hesitate at checkout. In an Uber Eats survey, 81% of consumers said that when they’re spending a lot on items, they don’t expect to pay extra for express delivery.

One way to address this is by offering free delivery. If that’s not possible, you can still reduce friction by making delivery costs predictable. For example, Uber One members get £0 delivery on eligible orders. Merchants can choose to opt into Uber One, gaining more visibility and access to high-frequency customers.

Many businesses also choose to provide free delivery on orders above a certain amount, letting the sale cover the cost. Promotions like these can help increase conversions and encourage larger purchases.

Everyone loves a freebie. You can attract new customers and encourage larger purchases by offering a “free item with a purchase” or “free item with a minimum order size” deal.

For example, a perfume retailer might offer a complimentary sample of a popular fragrance when customers spend $100 or more, giving customers an incentive to reach a certain spending threshold. Or a restaurant might offer a free dessert with a meal purchase, giving customers a taste of something new while increasing the average order size.

Some businesses keep customers coming back time and again—not just because of what they sell, but because they reward loyalty. Programmes that offer perks, points, or exclusive benefits give people a reason to return.

Take Starbucks Rewards: members earn stars on every purchase, which can be redeemed for free food and drinks. They also receive perks such as birthday treats, personalised offers that encourage larger purchases, and the convenience of mobile ordering and in-app payments.

For businesses, the real value of a loyalty programme like Starbucks Rewards is in the results.

Research shows that Starbucks Rewards has averaged 16% year-on-year growth and that rewards members are 5.6 times more likely to visit Starbucks daily than non-members. The programme also drives retention: 44% of Starbucks Rewards members return regularly, which is 19% higher than the industry average.

With Uber Eats, you can create your own loyalty programme in Uber Eats Manager. Offer rewards when customers spend a certain amount or order a set number of times, helping turn occasional buyers into regulars.

Offering discounts on specific items or categories is a great way to highlight what’s new, drive demand for seasonal favourites (like pumpkin spice lattes in the autumn), or encourage customers to try slower-moving items.

Many restaurants run “Save on Select Items” offers on Uber Eats, giving customers discounts on dishes they’d like to move faster. This can be an especially effective way to handle surplus ingredients or spark interest in higher-value items.

Retailers often find success with this strategy, too. On Uber Eats, Petco breaks savings into categories like Cat, Dog, Fish, and Reptile. Dog owners, for example, can browse the Dog category to see discounted items for their pets. Offers like these make it easy for customers to spot deals that matter to them while encouraging larger orders.

A “spend more, save more” promotion encourages customers to purchase a certain quantity or spend a set amount to unlock savings.

For example, a grocery shop could use this strategy on Uber Eats by creating offers such as “Buy 2, Save $2.50” on strawberries—a smart approach for products with a short shelf life. Similarly, a restaurant might offer a “Spend $25, Save $5” deal, encouraging customers to try new items and buy more than they may have originally planned.

Offers like these make it easy to help move stock while increasing order size and giving customers a clear incentive to spend more.

Rebates or cashback offers are a clever twist on traditional discounts that encourage repeat business. Instead of receiving a discount up front, customers earn a portion of their spending back as store credit or points—similar to how credit cards reward users.

Thrive Market uses this approach with the Thrive Cash programme on its website and app. Customers earn Thrive Cash by referring friends, reviewing products, or buying select brands. The earned cash is automatically applied to their next purchase, encouraging them to return. With an expiry date and redemption limited to merchandise, Thrive Cash also creates urgency, motivating customers to shop again before rewards expire.

Storewide sales give customers a discount—either a percentage off or a set pound amount—across a wide range of products.

Common examples include holiday sales, end-of-season discounts, anniversary events, back-to-school promotions, friends-and-family deals, and flash sales. These sales are usually limited in duration and feature significant discounts.

Some businesses also offer special discounts for specific groups, such as pensioners, students, or military personnel, showing appreciation while catering to different customer needs.

On Uber Eats, businesses can run digital storewide discounts, such as a percentage off an entire order once a customer reaches a specific spending threshold. For example, your restaurant might try offering 20% off orders of £35 or more.

When you think of happy hour, you probably imagine discounted drinks at your favourite place after work. But it’s not just for bars—any business can offer time-limited deals during quieter periods to boost demand.

Deals like these work because they encourage people to visit during off-peak hours—for example, the time between lunch and dinner—turning quieter periods into opportunities for extra sales. They also create a sense of urgency: customers know the deal won’t last all day, so they’re more likely to act quickly.

On Uber Eats, you can set discounts on selected items during a specific window, such as 2–5pm on weekdays. These happy hour offers help you attract business when things are quieter while protecting your margins during peak times.
