Back about 3-4 weeks ago, I got an open box 15" base model MBPc from Best Buy. Brought it home and put my 8gb Crucial RAM in. Then yesterday, found B&H photo pricing the 15" MBPr June, 2012 model for $1799.99 new. I called one of the last Best Buy's in my area that still had this model NIB in stock and they agreed to price match and exchange my MBPc. In my excitement, I wiped the MBPc and rushed out the door, to the store. I get home to set up my new precious and I realize I totally forgot to change out the RAM in the MBPc with the original 4gb RAM. I'm not butt hurt over the $50 I obviously won't get back for the RAM but I'm curious if this is any big deal or if there is any reason I should pursue getting the original 4gb RAM back to Best Buy? Has this happened to anyone, here, before?
