I purchased a washer and gas dryer from Lowe's. Originally the sales rep said there would be no installation charge, but by the time I reached the cash register that changed because they claimed a gas dryer installation costs extra. So I paid $153.00 for the gas dryer installation. I live in a new construction house. When the installer arrived, he claimed that the existing gas hookup was not standard and that it would cost an additional $100 for the install, and that they would have to come back another time. I spoke with Lowe's and they supported this claim. I told them that I wanted a refund for the $153.00, and that I would call a plumber myself. They said that it would cost me more than $253 for the install if I used my own plumber, but refunded my money anyway. A plumber came out and installed the dryer for $85.00.
Not sure if this were an intentional bait and switch, but I saved myself $168.00 by not taking Lowe's word for it...
