Also have some 505 inventory. I bought one at the DC store on Sat. My first reader (woo-hoo!)
They're also selling for $260, and if you want to play the credit card game, and buy $25 worth of other merchandise (depending on taxes - you need to break $299), you can get $100 off. Basically meaning that you get a $200 PRS-505 and a (eg) free $25 sony bookstore card.
Be aware that they have multiple credit card offers.
