If it is a PS3 license, those are supposed to start coming out later this afternoon I think...they were still testing things out before releasing them.

Many of the big-box stores will have a 48 hour or so delay on processing/sending codes sometimes. If you got it too late in the day, that delay may push you past the 2nd business day for processing so it may get pushed into a third day sometimes (like they may batch things and distribute them once a day or something, and yours hadn't processed yet).

We won't have access until the maintenance is done anyway--which is scheduled to not end until late Thursday night for the bulk of us. Hang in there...there are still like 7hours or something in Bentonville's core office hours. It may be in your inbox when you get home tonight.

Worst case scenario, you may be able to use an online digital option elsewhere, and cancel the Walmart order if it hasn't processed yet.
