If there is one thing I have learned in the 25 years I've been on this Earth, it's to not worry about things you can't change. When you go in the store, ask to price match it. If they say no, then deal with it and escalate it further if you really want to.Ok. YMMV. The employees I have talked to seem to be real sticklers.
This is from their website
Amazon.com, Bhphotovideo.com, Crutchfield.com, Dell.com, HP.com, Newegg.com, and TigerDirect.com.
However, you preordered the item knowing the price was $50 more. So in the end, if you don't get a price match, you can only be mad at yourself.
Stop worrying about things you can't change yourself.
