Always been fine for me, and I think they're returnable in the same way as other stuff (free, can even just throw at a clerk at UPS Store and you get refund same day), but I'd double-check specific feedback for any third-party seller.
Yeah, I have it and it looks good. They used the PC assets, supposedly.

Want to make sure folks are aware of the "Add $100, get $10" deal:

I can't find it on CAG, so I'll start a thread too.
Good point. Edited the OP to add this. I don't have this but enjoyed the demo. Played it more than any other demo I've ever downloaded, I think. Thanks!
A lot of Wii U games on sale at Amazon, including ones I can definitely vouch for as worth it:
Call of Duty: Black Ops II ($19.99)
ZombiU ($23.99)
Need for Speed: Most Wanted ($18.40...great deal)
Mass Effect 3 ($17.62 and says 9 left)
Assassin's Creed III ($19.57)
Tekken Tag Tournament 2...
Nice, the BB website says the closest store that has it is over a bridge with tolls, so I don't know if I'll be able to spring for this one. Was hoping for it to be in stock closer.
Good luck to you. FWIW, my Google searching suggests the site is legit and intended for academic licenses for software, but who knows what's up here. Probably submitted for 10 of them so they can list it, get attention on their site and then refund a bunch of people.
