On Thursday, Samsung Vibrant's launch day, Amazon.com one-upped T-Mobile's own store by offering an extra $50 discount off the phone's $199.99 price.

However, after seeing LetsTalk.com launch their offer of $99.99, Amazon.com didn't want to get left behind and now promptly followed suit, also dropping the price to $99.99 for new accounts.
