Yeah selling on eBay is a complete rip off! For any item you sell, they basically take 15%, rounded up, that's without shipping included. The lowest shipping price you can ship an item for is $1.93 and that's the lighest item possible.
The shipping fees only go up the heavier the item is. Plus you also have to buy the shipping material, tape, pack it all up, drive to the nearest post office, then stand in line for who knows how long, and then drive all the way back home which might be far away.
Protip: if you want to sell on eBay, make sure no one on Craigslist wants it first.
