Cash back timing depends on the merchant and affiliate network. Purchases usually need to be tracked, reported by the network, and confirmed before they become eligible for payout.
Sometimes, but tracking is most reliable when the coupon is listed by the merchant or StackWell. Unlisted codes, browser extensions, or switching tabs before checkout can cause some merchants to decline cashback.
