$1.50 for me now after a month 
You must be doing something wrong
Do you usually check if the items are relisted below your price? That way it'll probably take a long time to sell
I don't put any time into checking anything. I use the script and tell it to sell everything at the cheapest possible so it sells and then I don't check it for a few weeks and like 10-30 things sell for a couple cents each.
You're also probably playing games that don't really have a base that want to do badges.
Blazblue (the
first one correction: Cross-Tag Battle) is like $.25 per card, but selling it takes forever because not a lot of people/want to craft the badges. Over time, those animu titles will also crash and burn because of age and people selling their stuff for $.01-.02 less than the current lowest so folks buy THEIR stuff over the stuff currently listed.
Unless you're willing to sit there and monitor 100 cards you're better off not doing Idlemaster and just playing what you want and selling dupes, tbh.
