Perhaps, to save time and frustration, you should look at like items you would be selling and see if there is a market for them and if the closing price(s) is acceptable. Take off 20% of the closed total and that should get you close to what you get BEFORE you deduct the actual cost of the item. There is time, listing, handling, materials, bookkeeping to figure into the net you get. Also being new at this, you maybe a target for scams. Then there is the usual "fretting" about the closed sale, comebacks, do I, or do I not, add insurance and sig/conf. Make a few mistakes???probably, make different ones? probably all part of the "game".
