A lower price after you buy does not automatically mean a refund, but many retailers offer some form of price promise, price match or goodwill adjustment. This guide explains how to check the relevant UK policy, compare like-for-like offers, estimate the possible saving and make a clear claim without relying on an expired coupon or misleading advertised price.
Overview
There are two different situations to separate. A price match is normally requested before purchase, when another qualifying retailer is selling the same product for less. A price adjustment or price-drop claim is requested after purchase, when the original retailer reduces its own price or accepts a lower competing price within a stated period.
These promises are commercial terms rather than a universal right to receive the difference. The retailer may limit the offer by product, seller, location, delivery cost, stock status, membership, payment method or claim deadline. A retailer's general returns policy may also be separate from its price promise. Check the live terms for the exact shop and product before assuming that a claim will succeed.
The most reliable comparison is not simply the lowest headline price. Compare the final delivered cost, the condition and specification of the item, the identity of the seller and whether the competing offer can actually be bought. A marketplace listing, clearance item or one-time voucher may be excluded even when its displayed price is lower.
For wider deal research, pair this process with our flash sale buying checklist. It can help you verify stock, delivery terms and the real saving before a limited-time offer expires.
How to estimate the possible saving
Use a simple delivered-cost comparison rather than comparing product prices alone:
Potential saving = qualifying original cost − qualifying lower cost
For each side, record:
- the product price;
- delivery, installation or collection charges;
- any mandatory fees;
- the value of a coupon, voucher or automatic discount;
- the value of cashback only if the retailer's policy allows it to be counted; and
- any membership or subscription cost needed to obtain the competing price.
For example, suppose you paid £120 including delivery. The same retailer later lists the identical item at £105, with delivery still included. The apparent difference is £15. If the policy permits an adjustment and the request is within its time limit, £15 is the amount to ask about. If the later price requires a new-customer voucher that you could not have used on the original order, the retailer may treat it differently. Do not count the saving until the terms confirm that the offer qualifies.
For a competitor price match, compare the full cost at both retailers. A product listed at £100 may cost more than one listed at £104 once delivery, membership fees or required accessories are included. Record screenshots or save the product page showing the item name, model number, price, stock and delivery terms. Prices and stock can change quickly during flash deals.
Inputs and assumptions
Before contacting customer service, gather the inputs that determine eligibility. The following comparison table is a practical checklist for major UK retailers; it is not a statement that every retailer currently offers every type of protection. Policies change, so use the retailer's current price promise, help page or order support channel as the final authority.
| Retailer to check | Confirm before claiming | Evidence to prepare |
|---|---|---|
| Argos | Whether the relevant product range has a price promise, whether it covers a post-purchase drop and which sellers or offers are excluded. | Order number, product identifier, lower-price link or dated screenshot. |
| Currys | Whether the promise applies to online and store purchases, the eligibility window, delivery comparison and exclusions for promotions or marketplace offers. | Receipt or order confirmation, matching specification and competitor price evidence. |
| John Lewis | Whether its current promise covers the product category, competing retailer, promotional price and a claim after purchase. | Purchase record plus a live or saved page showing the comparable offer. |
| AO | Whether the policy applies to the exact appliance, delivery service and seller, and whether a lower price must be reported before ordering. | Model number, delivered-price calculation and order details. |
| Amazon UK | Whether the order is sold by Amazon or a marketplace seller and whether any price protection or refund route applies to that order. | Order page, seller name, product identifier and the lower-price evidence. |
| Tesco | Whether the relevant promise concerns grocery pricing, general merchandise, Clubcard pricing or a separate promotion, and which terms apply. | Receipt, Clubcard or promotion details where relevant, and comparable product information. |
For every retailer, check five questions: How long is the claim window? Does the comparison include delivery? Are marketplace sellers accepted? Are sale prices, clearance, coupon codes, cashback or member prices excluded? Must the claim be made before purchase, or can an existing order be adjusted?
“Identical” usually needs to mean more than a similar photograph. Match the brand, model or SKU, size, colour, quantity, condition, warranty and included accessories. A retailer may reject an offer from a third-party marketplace, auction site, private seller, outlet, trade-only supplier or retailer without available stock. A first-order discount, student discount, free-shipping code or percent-off coupon may also be treated as a separate promotion rather than a comparable public price.
Worked examples
Example 1: the retailer reduces its own price
You buy an appliance for £260 plus £10 delivery, making the qualifying cost £270. Five days later, the same retailer lists it at £240 with £10 delivery. The difference is £20. Check the adjustment window, product exclusions and whether the retailer calculates the difference from the amount actually paid or from a promotional price. If accepted, request £20 rather than simply asking for a general refund.
Example 2: a competitor has a lower offer
You find the same model at another retailer for £185, but delivery is £8 and the competing seller is a marketplace business. The comparable delivered cost is £193. If your retailer's delivered price is £205, the theoretical difference is £12, not £20. The claim may still fail if marketplace sellers are excluded, if the competitor has limited stock or if the lower price depends on a coupon that the policy does not recognise.
Example 3: a coupon changes the calculation
An item is £80, but a public voucher code reduces it to £72. If the retailer accepts voucher codes when calculating its own price, the relevant comparison might be £72. If the code is restricted to new customers or cannot be applied to the product, the retailer may compare the standard price instead. Save the code's conditions and do not assume that the largest visible discount is eligible.
A practical claim template
“Hello, I am contacting you about order [number], placed on [date], for [product and model/SKU]. I paid [amount including delivery]. The same qualifying item is now advertised by [retailer] at [lower amount], or is listed by [competitor] at [lower delivered amount]. The offer is available at [link] and was checked on [date and time]. Please could you confirm whether this qualifies under your current price promise or price-adjustment terms and, if so, process the difference of [amount]? I have attached my order confirmation and evidence of the comparable price.”
When to recalculate
Recheck the numbers and policy whenever the price, stock status, delivery charge or promotional conditions change. This is especially important during daily deals, flash sales, seasonal events and clearance periods, when a competing page may expire before the retailer reviews your claim.
Revisit this guide at least quarterly when maintaining a shopping checklist, and immediately after a retailer changes its terms. Update the claim window, excluded categories, treatment of marketplace sellers, coupon rules and the correct support route. Readers should also recalculate after a recent purchase drops in price, a retailer issues a new promo code or a lower offer appears elsewhere.
Keep a small record with the order date, item identifier, amount paid, delivery charge, policy link, claim deadline and evidence screenshot. That turns a vague hope of a refund into a checkable request. If the policy does not apply, compare the saving with the retailer's return costs and inconvenience before considering a return and repurchase.
