My grandpa used to work for Sears (late 80s/early 90s), loved them, they were awesome to work for, awesome to buy from, just awesome (in his opinion). So when I went shopping for new appliances I was shocked (shocked I tell you!) to hear him say "Buy from anywhere but Sears. Seriously anywhere. Go to Best Buy, but do not go to Sears", he hates Best Buy as well because they screwed up a computer of his years ago, so it was big that he suggested them.
Apparently they screwed up a couch he and my grandma bought. They were supposed to deliver it on a Tuesday. They did. Three weeks after they were supposed to deliver it. Three weeks after the charity had come and gotten the old couch. Grandpa kept getting transferred to everyone in the company in the three weeks leading up, and when he called to complain after it had arrived he was told "It's there now, that's what's important!", I'm not sure how he reacted but I'm guessing not e-hell approved.
