Utilizing the Price Match policy is only worthwhile if the item in question costs a lot, say in the few hundreds. In which Transformers will rarely cost that much domestically anyways.
Price matching is much more common when it comes to electronics, and sales are a lot more competitive.
Here is a
link from RFDs, it's an online guide to teach you how to Price Match properly and what to expect, which is especially useful when it comes to big ticket items (such as appliances, electronics, furniture). Really useful for some of the members here who are just starting a family/got a new home.
As for TRU's price match policy, I'd just buy it at Wal-Mart anyways, since their return policy is two times as long as TRU's (
90 days vs. TRU's
45 days), which can be useful for MISB'ers who have buyer's remorse, or someone who found a better deal loose or elsewhere.
