Collected observations, not a fresh retailer check. Unknown expiry does not establish an ongoing offer.
Understanding what the site records—and what it does not establish—helps you read a percentage, coupon duration or shopper-activity figure without giving it more weight than the evidence supports.
From collected listing to published page
The website reads JSON files under data/deals and data/best-deals at build time. Category routes are discovered from those files. The About page describes automatic collection from publicly available listing data; this website repository does not establish every upstream collection source or checkout-verification procedure. A renderable deal requires a non-empty ID, title and a product URL accepted by the existing URL validator. Optional fields include images, discount, code, expiry, timestamps and monthlySold. Each file’s generatedAt supplies its snapshot date.
Filtering and ordering are visible rules
The existing category grids offer descending discount order and, for deal categories, newest listing-update order, along with code and minimum-discount filters. The homepage’s trending shortlist applies a minimum of 100 recorded ratings and a recorded discount of at least 20%, then ranks by monthly shopper activity and discount percentage; it does not display those ratings. These guides have their own disclosed rules: positive discounts, exclusion of known expirations at build time, published category or keyword limits, and deduplication by ID. The activity shortlist orders monthlySold first; coupon guides require a code. Other guides order discount first. Stable ID ordering resolves remaining ties. The separate DealDino Rankings pages use centralized product-title and category filters over current inventory, not imported list membership. They require three matching offers, deduplicate by newest observation before excluding known expired offers, then order recorded discount descending, shopper activity descending and product ID ascending. Missing activity counts as zero; coupon observations do not change ranking order.
What observations can establish
Code seen for a number of days is the whole-day interval between codeFirstSeen and the source snapshot date. Missing timestamps or a first sighting after the snapshot produce no duration. It is not a checkout success rate or uninterrupted monitoring claim. monthlySold is the source’s recorded shopper-activity field, not DealDino-attributed sales. The website publishes static exports, so these figures advance when a new build publishes new data rather than whenever a visitor opens a page. Existing code controls recheck known expiry times in the browser.
The limits of a price-free shortlist
DealDino does not display Amazon prices or use these guides to claim historical lows. Discount percentages come from recorded listing fields, not an independent historical-price calculation. The median and relative positions compare eligible products within the stated snapshot pool only. An unknown expiry is not evidence of ongoing availability. Check the exact product, current price, seller, coupon conditions and final total on Amazon. DealDino may earn a commission from qualifying affiliate purchases at no additional cost to you; affiliate compensation does not determine guide ordering.
Common questions
Does a new page visit refresh the deal data?
No. The site is a static export. A new build updates selections from the dataset; browser expiry checks can mark an existing code expired, but do not fetch fresh retailer offers.
