So, apparently Target doesn't do price adjustments with receipts alone anymore. I went and tried, and they told me I had to bring the items in to return them first, then re-buy them for the sale price. Even though in the past, they've done this just by using the item numbers on the receipts. I jumped through their hoops, because fortunately, I hadn't opened most of what I picked up last week. So I got the discount on Solus, Prima, Megatronus, and the Aerialbots. It saved me about $55 so it was totally worth it. I already opened Red Alert and Grimlock and threw out their packages, so I gotta settle for the $15 off $75 (which brought 35+55 to 90, -15=75 anyway).
