Eddie Bauer's gave me full replacement value on a jacket (whose waistband had been ruined by a dry-cleaner) even though I had bought the item a few years before and on sale. That impressed me.
Back around that same time, I was the administrator of my department's computer network and did a lot of the repairs and upgrades myself. I called AT&T and asked for a price for an OEM 40Mb hard-drive for one of their PCs and it was so ludicrously high ($750 or so when bigger hard-disks were running about $1/Mb) that it's in the running as my worst retail experience, even though I didn't buy it and all it did was make me laugh into the telephone.
