Shipping costs not included on the invoice that came with the part.
The only reason I gave this transaction three stars was: I billed my customer for the part based on the invoice I received with the part. Several days later, I got another invoice by email that had an additional charge for shipping that was three times the cost of the part. The part arrived quickly, the price was reasonable and shipping costs were reasonable, but by the time I got the emailed invoice, It was too late to bill the customer for the shipping cost. I had to bear the shipping costs myself.
