You do realize they take less on the front end, but more on the back end, don't you?
What I hate most is the lack of transparency. Displaying the deposit, especially now that it's so low, is useless. I want to know right away how much a successful listing will cost me without pulling out a calculator every single time.
I noticed different costs for different items at same selling price and same listing time. Is there a guide somewhere that explains the math?
