Received email from JB Auto for oil change at discount.
I took advantage of offer, only reason I made appointment.
Looking closely at receipt I saw I was over charged.
I called to ask & was told it was tax plus extra's.
The math didn't work even with explanation I was given.
Asked about that & was told,
Next time I come in they'll take a dollar off.
A company's invoice must at some point match the offer no matter how much ignorance an employee exhibits
