Not in the rewards plan
Prices come from each shop’s own product feed and are checked daily; the shop’s own site always has the final price and delivery cost. AdvantageLife earns a commission when you buy through these links; it never changes the price you pay. For shops marked Team rewards, AdvantageLife shares that commission with qualifying members under the Deal Finder rewards plan once the shop has paid. Amazon purchases earn no member rewards.
