This is not an honest repair shop at all. Clearly all sales persons are commission based. My wife went to this store for an oil change with a coupon: 17.99 for an oil change plus filter and rotation. This is their officially released coupon sent to our mailbox, not some one line coupons. They did not want to honor it and said this coupon requires a synthetic oil change which is $36 and this coupon can take $7 off, and the final will be $29 plus tax. This is definitely up selling. Okay, my wife took it and asked if she can see the final invoice and pay upfront in case of anything surprising later. The cashier told her no you pay later. When they finished the work and showed my wife an invoice of $45 which includes an additional $10 labor fee, $3 shop supplies and $3 tax. This is fraudulent. I've never heard of any labor fee associated with a simple oil change when everything was agreed upon at the beginning. This is fraudulent way of doing business and definitely gender DISCRIMINATION. I'm also gong to report it to BBB and Conrad customer service. I am writing this to let you be aware of it and think about it before going to this store for any service. My purpose is to let them know who is going to pay it off at the end of the day.
