Sony is presently offering a deal, wherein you apply for Sony's credit card, and you can buy the Sony Reader for $50... that's $250 off the regular price. (
Details here.)
If you've been wanting the Sony Reader, but didn't want to pony up the 3 C-notes to get it (and if you're mature enough to not do anything stoopid with a new credit card), I'd suggest checking this deal out!
