OnBuy Discount Code & Voucher Code December 2025

Get Paid to Shop with OnBuy's Money-Back System

OnBuy has cracked the code on making shopping actually profitable. Instead of hunting for discount codes or wrestling with complicated loyalty schemes, they've built the savings right into every purchase. You earn 1% cashback on literally everything, get free delivery on loads of products, and can grab discounts reaching up to 77% off. It's like shopping at a permanent sale where the store pays you for browsing.

How to Apply Your OnBuy Discount Code

Getting your OnBuy voucher code to work is dead simple, but timing matters. Here's exactly how to lock in every penny of savings:

1. Add items to your basket and head to checkout when you're ready to buy
2. Spot the 'Discount Code' or 'Promo Code' box during checkout — usually near your order summary
3. Enter your code exactly as shown (mind the capital letters and spaces) and hit 'Apply'
4. Double-check your discount appears in the order total before completing purchase
5. Remember your 1% cashback stacks on top of most promotional codes for double savings

If your code won't play ball, check the terms and conditions — some codes are for new customers only or need minimum spend amounts. Even without a code, you're still banking that automatic 1% cashback on everything.

Earn Money Back on Every Single Purchase

This is where OnBuy absolutely shines. Their cashback system ditches complicated points schemes that take forever to understand. You earn 1% cashback on everything you buy, and it shows up instantly as your 'Price After Cashback' on every product page.

Flexible Cashback That Works for You

Your cashback is completely flexible — spend it straight away on your next OnBuy order, save it for something bigger, or withdraw it as real money to your bank account. Unlike Amazon Prime or other loyalty programs, there's no annual fee. Every purchase automatically earns cashback, whether you're buying a £5 phone case or a £500 laptop.

Over time, those 1% savings really stack up, especially if you're doing regular online shopping. It's money that actually belongs to you, not points that disappear or store credit that expires.

Score Free Delivery on Thousands of Products

OnBuy makes it dead easy to spot which products qualify for free shipping — just look for the '+Free Delivery' tag throughout their listings. No minimum spend requirements, no membership fees, just straightforward free shipping on loads of items.

For products with delivery charges, you'll see clear pricing like '+£2.99 Delivery' so there are no nasty surprises at checkout. This transparency means you can factor shipping costs into your decision-making and choose the best overall deal.

Hunt Down Bargains in Hot Deals and Hot Buys

OnBuy's Hot Deals and Hot Buys sections are treasure troves of their most aggressive discounts. These aren't random markdowns — they're carefully curated deals on trending products people actually want.

Spot the Best Savings

You'll find discounts from 5% off everyday items up to 77% off selected products. The deals span everything from projectors and perfumes to meal replacement shakes and skincare. OnBuy highlights percentage savings with bold labels, so you can spot the best bargains instantly.

These sections update regularly, so it's worth checking back if you're not in a rush. The combination of marked-down prices plus automatic 1% cashback delivers seriously good value, especially when many discounted items still qualify for free delivery.

Newsletter Perks and New Customer Benefits

Signing up for OnBuy's newsletter is a no-brainer move that takes 30 seconds and pays off for months. Subscribers get early notifications about the best discount codes and deals, putting you first in line when the good stuff goes live.

Exclusive Access and Early Alerts

New customers often access exclusive welcome offers, and the newsletter keeps you updated on seasonal promotions like their 'Christmas comes with Cashback!' campaigns. You'll hear about special offers on leading brands before they hit the main site.

The emails focus on genuinely good deals rather than flooding your inbox with daily spam. It's the kind of newsletter that actually saves you money rather than just trying to get you to spend more.

Major Shopping Events and Seasonal Sales

OnBuy goes all-out for big shopping events, with dedicated sections for Black Friday, Cyber Monday, and Prime Day-style sales. These events feature their deepest discounts of the year, with savings well beyond usual ranges.

During these sales periods, you'll find deals across every category — tech, home goods, fashion, and beauty. The smart move is combining these event discounts with your automatic cashback for maximum savings.

NHS Staff Discounts and Special Offers

NHS staff can access special offers through the Bluelight Discount scheme, typically providing around 10% off purchases. This stacks nicely with the automatic 1% cashback system for extra savings on everything from work essentials to personal purchases.

Solid Returns Policy and Buyer Protection

OnBuy backs up their deals with robust customer protection. You get a standard 30-day return policy on purchases, plus 180-day buyer protection. If something doesn't arrive or doesn't match the description, OnBuy steps in to help sort things out.

Shop with Confidence

This protection is especially valuable when buying from a marketplace with multiple sellers. The returns process is simple, and extended buyer protection means you can shop with confidence. It's one reason OnBuy has earned recognition as a trusted marketplace, backed by over 111,000 customer reviews on Trustpilot.

Compare Sellers for Maximum Value

Here's a pro tip many OnBuy shoppers miss: the same product might be available from multiple sellers at different prices. Compare not just the base price, but delivery costs and seller ratings too.

Sometimes a slightly higher product price from a highly-rated seller with free delivery works out cheaper than a lower price with shipping charges. Factor in your 1% cashback on the total purchase price to work out which option gives the best value.
