I was able to pick up a PRS-T1 at a local FRYs in Southern California a few weeks back for $79, so I don't see the $99 dollar price that Best Buy is listing as anything special.
This was for a brand new in the box PRS-T1, not refurbished or open item.
In any case, I have totally given up on Best Buy, and no longer even bother with them, because, in my experience, 90 plus percent of the time, their special 'SALE' items are NOT IN STOCK (they are just trying to get you into the store for a bait-and-switch rip-off.)
Still, having had a chance to play with my PRS-T1, I do agree that it would still be an outstanding deal at $99 so if you were lucky enough to find one at that price . . .
