Our local Toys R Us was sold out but a friend took the ad to Walmart and they matched it for $85, though I'm not sure if he had to argue or what.
Yeah Walmart is real big on being the lowest priced right now and if you take in the add they most likely will price match. They were even doing matches on black friday. There are some rules like no gimmick ads such as: buy one get one, buy one item to get another, % off, etc. And certain things are left up to the store manager and/or district/market manager such as how far from the store you are matching is but if you argue or call the 1 800 # you can usually get them to match if your request is reasonable and you are calm.
I just told them I wanted the advertised price of 109.99 and understood if they couldn't give the giftcard as well and everything went smoothly with none of the calling to confirm if it is in stock at TRU crap. All that was required was a manager override because of the price difference. But just pick up the bundle and go to any cashier with your TRU ad in hand to start the process as there is no need to go to customer service since their cashiers are able to price match.
On a side note.. best buy absolutely refused to match that price for me.
