Listing is 30 cents but there is a long running promotion that gives sellers 50 free listings every month
If eBay does its job and finds you a customer, they get fees.
In most categories that is 10% of the selling price PLUS 10% of the shipping price.
In addition if your customer's payment is processed by Paypal they will charge you 30 cents plus 2.9% of the payment.
If you were charged $100 as a selling fee, you must have sold something that your customer paid about $1000 (price+shipping) for.
It is also possible that you used a lot of different options --all of which are non-refundable and all of which, in my opinion, are useless.
The one that is least useful and less understood is Reserve on an auction, which will be charged even if the item does not sell.
If you list an auction with a starting bid of 99 cents and a Reserve of $1000 you will be charged $100 whether it sells or not.
If you list an auction with a starting bid of $1000 and it does not sell, you will be charged no fees at all. And no one can bid less than $1000 so the opening bid is a sort of reserve.
for a couple days
Hmm- did you run a three day auction? Fees are higher for those because eBay discourages them. They were all too often used by scammers who would take the money and disappear. They are seen by very few bidders in the short time period. And buyers are already wary of new sellers with little feedback selling expensive items with little time to consider.
If none of these apply to you, leave the auction number and you may learn where you went wrong.
