Buyer questions
Do you earn a commission if I click Check price?
Yes. Check price uses affiliate links to merchants. OfferLuck may earn a commission at no extra cost to you. Brands cannot buy a better percent-off stamp or sort position. Full disclosure is on the Affiliate disclosure page.
How does OfferLuck sort the deals board?
OfferLuck sorts in-stock deals by verified percent OFF, then by the live price from our last check. A discount appears only when a prior or list price exists and is not inverted. Listings without a verified list price stay off the public board.
When do you show a percent-off?
Only when we have a prior or list price we can stand behind next to the live sale price. If the numbers would require a guess, we omit the percent OFF and keep the row off the public board. The live merchant listing wins if the cart disagrees.
Do you publish star ratings or awards?
No. OfferLuck does not invent star ratings, awards, or lab scores. Images and titles come from the merchant listing. Always confirm price, stock, and fit on the live page before you buy.
