Recently I purchased a Lube N Go groupon for an oil and tire change, then called the shop to ask how much extra it would cost for synthetic oil. I was told $20. However, after I arrived I was told it would actually be $40, and was eventually charged about $48+tax. I called the manager to point this out, but he would not acknowledge the mistake made by his employee or offer to rectify it. Too often, I’ve found mechanics give wrong or misleading information about prices. This was no different.
