Uh, I was annoyed enough that I didn't manage to grab a Vita copy after getting the PS4 one, but now it appears I may not even had bought that one! Nothing's showing on my account order history. I am going to royally pissed if I missed both of them.
edit: OK, I guess I figured out what happened. Somehow I got logged off even though I had just logged in 5 minutes before the orders went up. The site created a different account based on my Paypal email address since it thought I was doing a guest checkout. At least I didn't miss my PS4 order, it's now associated with this other account. This could have been avoided if the store wasn't logging people off in such a short amount of time, but I guess it's all good.
