Had that problem from the same parts store years ago. Owner would have one price and the worker for him had another. When I asked the owner who was charging me the higher prices than his employee he said prices went up. Later on the same thing kept happening depending which one you were buying from. At that time I was working for the local Conservation District part time as well as the farm part time so I went in wearing a couple hats and it seemed like the owner was trying to stick it to the Conservation District so he lost my business 30 years ago because of other issues too. He retired and sold out a year ago so I should try going back in the store sometime as there is a great young owner there now.
