I bought a 32gb yesterday from office depot for 215 bucks, after a 35 dollars discount code: 182715056
I ordered online and pick up in store.
This is my 4th nexus 7. Love it
Seems you got lucky, the code was invalidated shortly after that and it seems they're not even selling it online at the moment. Probably dealing with the backlog of orders, some people actually had their orders canceled. They barely have it in stock around here, one nearby store has 1 in stock, another three are out, and the one location that's an hour away has several.
I'm just waiting for it to come back in stock at Newegg, without taxes and with free shipping it'll be $20 more at most (compared to the Office Depot deal), good enough. They've been out since the weekend tho.
