Anyone using Chase QuickPay for buying and selling? Here's a description--
Someone just used it yesterday to reimburse me for something, and it was quick and easy and didn't involve any fees. We both have Chase accounts in the same state, and I would assume this works only within the US, but the FAQ says only one of the participants in the transaction needs to have a Chase checking account.
Unlike PayPal, it doesn't offer buyer protection, and it doesn't allow you to accept credit cards. It's just for bank-to-bank transfers, but that could cover a fair number of situations, no fees required.
