So when you download your reports in EPN there is a field ebay total. I got an entry that says ebay total 1302.54 and my commission was 43.36 doesn't that seem low to you?
I think the 1302.54 is the item sale price, and 43.36 is ebay's cut on that sale. Your commission should be 21.68, or half of the 43.36 that ebay got. They don't, at least from what i've seen, list our commissions in the reports.
