I mentioned earlier in the thread how I managed to contact Target and indeed got them to price match(the Walmart price has since changed back to 300, so idk what was up with it all, but I obviously don't care now, haha).
I did not want to take a chance with them screwing up my preorder though(accidentally canceling or anything) so I mentioned upfront that I would be willing to take a Target gift card for the $15 difference and chose an e-gift card, which I got not long after.
