Thanks for bringing this to my attention everyone, here's the PM I sent to antlp89:
"Hey, sorry I haven't written to you sooner. I checked with the post office today to see what the hold-up was with your shipment, and it looks like I screwed up. With that first group, I shipped the local packages media mail and the stuff further away priority, and yours got lumped in the media mail by mistake. My apologies, and if the games haven't shown up in a week or so, I'll go ahead and refund your money. Again, sorry for the inconvenience."
So, the short answer is that I'm an idiot.
