Price evidence
Check Was Prices, RRP and Price History Before Buying
Was price, recommended retail price and price history answer different questions. A retailer's previous price describes its own comparison under stated conditions, an RRP is a manufacturer reference, and tracked history records observations from particular sources and times. None alone proves what a product is worth to a household today.
A fair check keeps the exact model, configuration, seller and delivery terms attached to every number. It then compares suitable alternatives in the current market. This removes some drama from a crossed-out figure and replaces it with evidence you can explain, even when the result is to buy at a modest reduction or wait.
A large saving can appear convincing when the reference price came from a limited selling period, a different seller or an RRP that does not reflect what shoppers normally pay for the exact product.
You will identify what each comparison figure represents, examine evidence for the same model and seller, and decide value from current alternatives and the delivered basket.
Label every reference price
Copy the wording attached to the comparison price, not only the number. Separate a retailer’s previous price, a manufacturer’s recommended price and a claim about typical market prices into different fields. ASA guidance on promotional savings explains why the reference behind a discount matters, while its RRP guidance addresses a different comparison. As a shopper, use those distinctions to ask what the higher price represents. Do not conclude that an advertisement breaches a rule merely because you have not personally seen the product sold at that figure.
Check whether membership, a trade-in, subscription, multibuy or voucher is required to reach the promoted figure. A price available only to a defined group belongs in a separate row from the public price. Where tax, delivery or service charges apply to one channel, include them before saying two figures are comparable.
Match the exact product and seller
Identify the product using the full model code or barcode, then record size, capacity, colour where relevant, condition and supplied components. If one offer includes installation or a subscription, separate those elements instead of treating it as a bare-product history point. Check whether a retailer-exclusive suffix identifies a different specification. Where the seller cannot confirm equivalence, keep the offers as alternatives with stated differences; calculating an exact saving between uncertain variants gives the comparison more confidence than the evidence deserves.
Keep first-party retail, marketplace sellers, refurbished stock and private resale separate. Seller identity changes fulfilment, returns and support as well as price. When a comparison page groups offers, open the underlying listing and confirm stock and seller before recording it; an outdated card is not a current alternative.
Read history as observations
Read a price chart as a record of observations from named sources over a defined period. Check whether it tracks a particular seller, marketplace offers or an aggregated lowest price, and whether stock availability is visible. A plotted low might exclude delivery, require a code or refer to a seller you would not choose. Describe it as an observed price within that coverage. Save the chart date and source, and use blank periods as uncertainty rather than assuming the missing days held the same price.
Look for repeated ordinary selling levels rather than anchoring on one brief high or low. If the product is new or has sparse records, reduce confidence and compare close alternatives instead of inventing a normal. Note model succession as well, because an older version may fall when a replacement arrives without becoming the right specification.
Decide from present-day value
Build two current baskets: the exact product you are considering and the best suitable alternative you can actually buy. Include the same required accessories, delivery and services, and check seller identity at checkout. Ask what the extra spend buys if the promoted product still costs more. A useful discount does not require the largest advertised percentage, and an impressive percentage does not create a need for the item. Set the maximum you would pay for the required outcome before looking again at the crossed-out figure.
Save the evidence date and checkout total, then choose a stopping rule. If the item is needed and the current proposition is sound, a historical minimum is not mandatory. If it is optional and the evidence is weak, waiting preserves choice. Either decision is more defensible than calculating value from RRP alone.
Questions Shoppers Ask
Is RRP the same as the price a retailer usually charged?
No. RRP is a recommended reference from the manufacturer or supplier, while a retailer's usual or previous selling price is a separate claim. Read the label and evidence attached to each figure.
Can price history prove the lowest price the product has ever had?
Only within the sources, period and observations the history actually covers. It may omit other sellers, private member prices or gaps, so describe the finding narrowly and still compare today's complete baskets.
