Believe it or not that Toys'r'Us has the same policy here in Canada for returns (used to be up to 90 days I think) yet they DO NOT do price protection. Even after I explained to them the steps I could take to defeat their stupid stance.

I went in one time with receipt asking if I could get the difference back. They woulnd't do it. So, I told them what I was about to do and did it: I went into the store, grabbed the same item I already owned, paid the new lower price for it and then went straight back to the returns counter. I returned it on the original receipt which was obviously for the higher price. I told them "thanks!"
