INSIST ON ESTIMATE BEFORE WORK IS DONE!!!Yesterday I went to Walmart's Auto Center to have four carry-in tires put on the vehicle. When they called me to pay because they were done, they presented me with a bill for $105.40. I hit the roof and in disbelief asked for an explanation itemizing how this fanastic figure was arrived at. They pointed to a list of services on the wall and explained how they stacked fees on the bill even when services would be double-billed under different itemized headings. They had NOT presented me with a pre-work estimate for this travesty, and it absolutely went way beyond what would be referred to as "reasonable expectation" fee-for-services.ANY other tire service center would probably have been half the cost!I would NEVER RECOMMEND these THIEVES!!!
