Yahoo! Shopping US launched the beta of their new Coupon Center last week. This release is quite appealing, very Web 2.0 yet simple to use. As long as you have a Yahoo! account, you can bookmark coupons you are interested in, vote for your favorites one, share them with your friends (using mail or Yahoo! Messenger), comment them. As a standalone tool (I mean not integrated in the main Yahoo! Shopping site), it’s almost perfect; the only basic feature that is missing is a full-text search, I think. Congrats to the team!
