CartRevolt

CartRevolt is a free community deals site. Tell it what you need, a few interests or a whole new-home checklist, and you see the deals that match, each with the reason it's there.

Members post deals, coupons and invite codes, then say whether a code worked. When two members say a code failed within 48 hours, it's marked as not working for everyone, so the next person doesn't find out at checkout. Every live deal's store link is checked once a day, and deals that are gone or sold out are marked ended.

You'll also find hidden clearance members found at Walmart and Target, gift cards below face value at Costco, Sam's Club and BJ's, free kids events, shopping hacks, and giveaways you can check yourself. It's free on the web, on iPhone and Android, and as a Chrome extension that tries members' codes at checkout.
