A PRACTICAL GUIDE · INDEPENDENTLY RESEARCHED
Voucher Codes and Discounts: Find Offers That Actually Work
A good discount makes something you already need cost less. VoucherBro helps UK shoppers find genuine offers, understand the small print and compare the final price before paying. Start with the retailer, check the conditions and let the checkout total decide. This is an independent shopping guide, not a live voucher-code directory.

Find genuine offers without chasing every code
Start with the shop you intend to buy from. Its offers page, app and email newsletter may explain a promotion more clearly than a copied code on another website. A newsletter welcome offer can be useful if you want the purchase and are comfortable subscribing; check who qualifies and how to unsubscribe.
Use a voucher source as a starting point, then read the retailer's own conditions. Check when the offer was published, what it covers and whether the shop recognises it. A claim that a code is verified does not mean it will work for your basket. Personal offers may be tied to an account and should not be treated as public codes.
Read the conditions before filling your basket
Look for an expiry date, a qualifying spend, eligible products and account restrictions. Find out whether the minimum applies before or after discounts and whether delivery counts. A code described as online-only may not work in a shop, while an app offer may need the app.
Retailers set their own rules. For example, John Lewis says only one promotional code can be used per order unless the individual offer says otherwise, and that a valid product must be in the basket. Treat this as a retailer example, not a rule for every shop. Read the actual offer before adding something just to reach a threshold.
A discount is only useful if the final price is better
Write down the delivered price of the exact item before applying a code. Compare the same size, specification and condition elsewhere, including delivery and any unavoidable charges. A large percentage off a higher starting price can still leave a more expensive basket.
Here is a worked example, not a current offer: on an £80 eligible basket, 20% off saves £16. With £4 delivery, you pay £68. A £15 code with free delivery gives a £65 total, so the smaller headline discount is £3 cheaper. Use the calculator below to try your own figures. Check the checkout again because excluded items, minimum spends and retailer rounding can change the result.
Combine savings only when the terms allow it
A sale price, voucher, loyalty reward and cashback offer are different things. They may combine, but there is no universal stacking rule. Check both the shop's offer and the cashback provider's merchant terms before deciding. A reward you cannot redeem on this purchase does not reduce today's bill.
TopCashback identifies using a voucher not displayed on its site as one reason cashback can be declined. Keep the order confirmation and read the tracking and claim instructions if using cashback. Compare the checkout price without assuming cashback will be paid: a visible discount and a possible later reward are not the same certainty.
Pause when a voucher asks for too much
An unfamiliar message offering a huge discount can lead to a fake shop. The National Cyber Security Centre recommends checking that a shop is legitimate and avoiding uncertain links. Type the retailer's known address yourself or locate it carefully through search rather than following a surprise text. Check the domain spelling, contact information and independent evidence.
Do not give a voucher website a retailer password, payment-card details or a one-time banking code to unlock a discount. Provide only the details needed at the genuine checkout. If a message creates pressure to act immediately, pause and verify it independently. Familiar logos alone do not establish that a website is genuine.
Your two-minute checkout checklist
Ask yourself: was I planning to buy this? Does the exact product qualify? Is the code still within its dates? Am I eligible? Did the discount actually appear before payment? What is the delivered total?
Remove extras added only to chase a saving unless you really need them. Save the promotion terms and order confirmation where useful. If the code fails, compare the undiscounted total rather than repeatedly changing the basket until the offer seems attractive. For a retailer-specific problem, use its official customer-service route. VoucherBro does not issue codes or handle retailer orders.
How to use this guide
This page explains shopping checks and provides an arithmetic tool. It does not promise that a code is available, endorse a particular merchant or publish invented offers. Linked provider pages are examples and sources, not evidence of a commercial partnership.
Conditions can change, so follow the current offer terms. Use the correction form to suggest an improvement to this guide, but contact the retailer about orders, refunds or rejected codes. Do not send payment details or account passwords in the form.
FAQ: Why is my voucher code not working?
Check the spelling, closing date, basket contents, minimum spend and account eligibility. Look for exclusions and whether the promotion applies online, in an app or in store. A code may be personal or incompatible with another offer. Confirm the current terms on the retailer's own website; if it should qualify, ask its customer-service team before paying.
FAQ: Can I use more than one voucher code?
Only if the retailer and the particular promotions permit it. A checkout accepting one code does not necessarily accept two, and combining a code with a sale price is a separate question. Read the individual offer rather than relying on another shopper's experience. John Lewis, for example, normally permits one promotional code per order unless the offer says otherwise.
FAQ: Is a percentage discount better than money off?
It depends on the eligible basket and delivery. Before delivery, 20% of £80 is £16, which beats £15 off. But £4 delivery on the percentage option makes its £68 total more expensive than £65 with the fixed discount and free delivery. Compare complete totals with the calculator, then confirm the actual checkout.
FAQ: Can I use a discount code with cashback?
Sometimes, but only under the provider's and merchant's conditions. An unapproved code can invalidate cashback even if the shop accepts it. TopCashback lists codes not displayed on its site among possible decline reasons. Check the merchant page and exclusions, and do not budget on cashback that has not been confirmed.
FAQ: How can I tell if a voucher website is a scam?
Be cautious about surprising messages, lookalike domains, unrealistic discounts and requests for payment or sensitive account details just to obtain a code. Check the retailer independently instead of trusting a logo or a link. The NCSC explains how to investigate shops and report suspicious messages or websites. If you have disclosed bank details or made a suspicious payment, contact your bank using its official contact details.
CHECK THE CHECKOUT TOTAL
Which discount is better?
Compare a percentage code with a fixed amount off the same eligible basket. Include delivery for each option. This checks the arithmetic, not whether a retailer will accept a code.
Assumes the whole basket qualifies, delivery is charged after the discount and no other fees apply. Fixed discounts are capped at the basket value. It does not model minimum spends, excluded items, discount caps, cashback, taxes or retailer-specific rounding. Check the actual checkout total. Your figures stay in this tab and are cleared on reload.
