I took advantage of the current sale at Best Buy for the PC version. Unfortunately, the idiot in me forgot to open up the box in front of the cashier to make sure that there's a serial code inside. True enough, my horrors of finding no game key have been realized. There wasn't a sticker, leaflet, or printout anywhere in the box and manual. I went back to the store an hour later, and after a long back-and-forth between the employees, they've basically told me to pray that Bethesda support will be able to help me. I'm just wondering if anyone has experienced the same thing. Any advice or response is appreciated, thanks.

Ah thank you for the link. I was thinking about waiting until tomorrow to call them, but it wouldn't hurt to shoot an email too.
