They did it for me...ours is a small TRU and they have a very minimal carseat selection. They ordered (from another store in-state) it for me and I paid upon delivery (when I brought my seat in to trade) This works best at the start of the Great Trade In because of the timeframe they have to work with..I had zero problems here. They were super helpful. (plus the prices are better right at the start, they up them during the trade-in.)
Okay let me clarify..after reading what my ADHD mind wrote...I live in a small N.Mich town, our Toys R Us is SMALL, I was set on the Britax FR85 (On-line it was $223) I went to our store and asked them if they could order it for me and if I could still get the Trade-in Deal. They told me no problem. They had to call around to find this seat as the warehouse was out as were many stores. They found it, ordered it and when it came to the store four days later the price on line reflected a huge jump. 269$ I mentioned this to them because if it had been in the store I would have bought it that day. Well, to make a long story short, I lucked out..they honored it. I suppposed it depends on who you are dealing with etc. Good luck.
