Does the in cart price from best buy (online) transfer over to the in store price?

I'm going to buy a Nikon D3100 and at best buy they have it on sale for 550 instead of 650 but only the in cart price. And i was wondering if i wanted to just go buy it from the store, if it will still be 550 or if that is only an online thing.

It is an online thing.

you should have read the terms and agreement at the bottom of the page, the prices are not transferable to their subsidiary branches.
