My question is, Does Gamestop, through whatever company they use (UPS/Fedex) still uphold the next day shipping kind of thing when they ship late? Like if they sent it Saturday, obviously it wouldn't come Sunday but it'll be here Monday? (which is today) :ahhh:
That depends on what shipping service they use (i.e. UPS, FedEx, USPS) and what service level was selected (i.e. next day/overnight, 2 day/express, etc.). If they used UPS, shipped next day air and it entered the UPS system on Saturday, you should receive Skyrim by 5PM today.
Since this is Gamestop we're talking about, I wouldn't hold my breath. I've never been impressed with their "customer service".
