DEX evidence centre
Check what has actually been observed about a deal or product, when it was checked and which market or variant it covers. This centre publishes only observations that have passed a separate review; an entry in the catalogue is not itself proof that a price, code or availability claim works for you.
Retailers control their checkout prices, eligibility and availability, which can change after a check. A missing or blocked observation means the claim has not been independently established here; it does not mean the original listing has been removed, corrected or confirmed.
How to use an evidence result
- Copy the exact Tailored Deals product or offer address into the lookup below. A retailer name alone may cover several different listings.
- Match the observation's market, currency, variant and eligibility to the purchase you are considering.
- Read what was checked and when. A retailer-page visit is different from applying a code in an eligible basket, and either can become outdated.
If there is no published observation, use the original listing as a starting point and confirm the details directly with the retailer.
What the evidence terms mean
- DEX Source Checked
- A named source supported a particular claim at a recorded time. This is not a checkout test.
- DEX Retailer Checked
- A retailer observation is recorded with its scope. It does not establish product quality or every shopper’s eligibility.
- DEX Code Tested
- An actual permitted checkout test must record the code, market and account conditions. One successful test is not a universal guarantee.
- DEX Price Drop
- A comparison needs dated prices for the same variant and market. An advertised percentage alone is insufficient evidence.
- DEX Needs Recheck
- Evidence is missing, stale, contradicted or inaccessible. Blocked access is never counted as a successful check.
- DEX Expired
- Expiry is an evidence outcome. Accounting for an expired offer is not calling it active; the original catalogue record remains protected.
Coverage and limitations
Published observations cover individual listings. We have not established what proportion of the complete catalogue has been independently checked, so we do not publish a verification percentage. These observations do not mean every offer is continuously tested or that a purchase has been completed.
Sponsored exposure cannot purchase a positive evidence result. These explanations describe this evidence centre and do not replace review of claims elsewhere on the site.
Corrections and appeals
Prepare a correction report with the original URL, evidence reference, market and what happened. Please omit passwords, payment details and sensitive screenshots. A later contradiction can reopen an investigation; any published correction keeps its earlier history.
