Samsung Galaxy Tab 2 10.1 w/ 16Gb & Case - $340 @ Costco
Costco currently has the Samsung Galaxy Tab 2 10.1 w/ 16GB & Case for $340 (includes a $40 Instant Rebate - expires 9/09/12).
Since this is in-store only (not online), I've attached a picture. the sign in picture does not say "Tab 2", but the package itself says "Tab 2".
Not an incredible deal by any means, but about the cheapest I've come across so far.
