Yahoo has launched a new shopping portal at shopping.yahoo.com/cashback. They’ve partnered with Rakuten/Ebates for the portal. In fact, payments track through your Rakuten/Ebates account, so Yahoo is really just the front. See the FAQ here.
I guess the idea is to mainstream shopping portals for people who aren’t used to it, and Yahoo is a more well-known company. Looks like this may also be available somehow in Yahoo Mail for those who use that.
The rates seem largely the same as with Ebates directly. I do, however, see some featured rates that are 1-2% higher. Not sure how this account will interact with the Ebates Membership Rewards version account.
Overall, it may not be worth dealing with another go-between for an occasional slightly higher rate, though heavy shoppers might find it worthwhile. Let us know if you see anything more interesting about this new portal option.
