I was under the impression that you can not bill the fees that a credit card company charges you as a separate line item on an invoice. With that being said, what I had understood it to be was that you can obviously include that fee as an item in the bill, but NOT as a separate line item. However, when I am sending out our invoices I do offer a cash or check discount equal to the credit card fee if the customer wants to pay that way. All that leads me to my next question. Today I went out to purchase a new gooseneck trailer. Before I even set foot on the lot that I was to purchase the trailer from I had received other bids (trailer + tt&l ....an out the door price) on comparable models at other dealerships including the one I went to get the trailer from. When I got down to signing the papers, the sales guy had added the additional credit fees to the total invoice .... as an additional line item. Thus changing the price he had quoted me over the phone. Needless to say, I went ahead and finished the transaction...possibly a bad move, I know. None the less I feel that I should have a decent case against the owner of the company, as there are some other things that are not right with the trailer which I found after I returned home and went over the trailer in greater detail. So my main question is this, does he owe me the credit fee back do his lack of following procedure for the sale? Thanks for the help.
