Wikibuy from Capital One
"it's like a magic button for shopping" Wikibuy is powered by a community of over 1 million users who share prices and coupons found in real-time while they shop. When a coupon code works for one person, the next person gets that code applied at checkout, automatically. When the community knows a lower price is available at another store, you'll be notified, automatically, right in your browser. Wikibuyers also earn loyalty rewards at stores like Walmart, eBay, and Macy's. The credits you earn can redeemed for gift cards on Wikibuy.com. Check out the reviews. It's real and it works.
