You may notice the price of items listed on our eBay storefront is higher than the price listed on COMC. This difference in price is due to the Traditional Order Premium. Please see the below Traditional Order Premium (TOP) Calculator. You can open this spreadsheet, enable editing, input a specific asking price, and the calculator will display the final, modified price as seen on eBay. Additionally, you can click the cells in the spreadsheet and examine the formulae to see exactly how the calculation is made.
