The Best Buy closest to me has a huge selection of E-Readers.
They have:
Kindle 3 Wifi KSO-In Stock
Kindle DX-In Stock
Nook-In Stock
NookColor-In Stock
Nook STR-In Stock but no display model. Kinda weird.
PRS-350 Only 3 left not replenishing
PRS-950 Display model only. Its been pretty beat up to.
Kobo Wifi-In Stock
Kobo Touch-Just a sign but no stock yet.
Its actually a pretty nice setup back by where the tablets are.
