I have sold an LP record and an EP record. When the buyer paid I found that he had ben charged $2 shipping for the LP and $2 shipping for the EP. I checked my listing and found that if I looked at the shipping cost for the LP it was $10 (which is what I charge). Shipping for both LP and EP would have totalled $10. Why has eBay invoiced the buyer for $2 each for the LP and EP?
