to figure out how much fees will be deducted per sale. If I were you, I would list one auction starting low to attract buyer - then cross promotion to BIN at the price desire. I would recommend that you list ONE single BIN with all the available sets you have (25 available if you want to do set of 4), this is minimize your listing fees on ebay.
Use the tool, it works out really accurate!!
