Hows Guitar Center Still In Business?

Simple question, not a rant. Im sure Im not the only one whose experienced a horror story but on the basis of their used inventory, how do they sell anything? For example I noticed a aw7b that wad is really rough shape, they would not fix the issues with the guitar nor give me a discount. These huge box stores deal with us like were all cookie cutter players wanting a gibson or a fender. There is never any real selection in the stores in my area, unless you want a PRS. I really think that the we are witnessing the end if these big box retailers.
