Several years ago I wanted a new pack.  Something smaller than a 5000 cu in megapack.  REI had a sale going on - 20% off coupon, etc.  I went in to the flagship store.  It was packed.  I had to wait in line just to talk with the salesman.  He was totally rude.  I wanted to try 2-4 packs on with simulated weight, run up and down the stairs, etc, and get feedback from him.  He looked more annoyed.  I said "fuck it" and walked over to Feathered Friends.  It was almost empty in there.  A guy was very helpful.  He didn't pressure me or bother me.  I tried on 3-4 packs, and left without buying anything.  I went to Marmot Mountain Works.  They didn't have anything different/better than FF's selection.  Next day, I went back to FF and bought one of the packs I had tried.  It was 20% more expensive than REI.  That was my middle finger to REI and thumbs up to FF.
