Google's Wallet-powered peer-to-peer payment service launched to rival Paypal was announced on May 15th and came with an interesting promotion: waived fees for transfers funded by credit cards. This promotion was recently (possibly today) adjusted quite drastically, and now only payments less than $250 aren't charged fees. Additionally, we now know that the promotional period ends on June 29th.

Typically, credit card-funded transfers are charged a fee of 2.9% with a minimum of $0.30, but for a previously undefined "limited time," Google decided to foot the bill in hopes of attracting initial users.
