Walts Service

Walts Service in Amherst NH, quoted me $375-$to replace the left front wheel bearing on my Audi AI accepted the quote and dropped my car of to have it repaired
When I picked up the vehicle that same afternoon, I was presented with a bill in the amount of $which is more than 60% above the original quoted repair cost
Parts: $
Labor: $
Total: $
I have no problem with auto repair shops marking up the cost of parts, but in this case, the part was marked up 330%, which I find totally outrageous
The parts used in the repair are as follows:
WHEEL BEARING KIT (82MM, SKF)
OEM: 8EXXXXXXXB
MPN: WKH
Manufactured By SKF (Audi original bearing supplier)
Online price: $including all new bolts required to perform the repair
Walts Service charged me $for something they purchased for $
