Seeing as you're asking Paypal money for your CSGO skins, you're actually overcharging for even those. I don't see how you'll ever actually sell this stuff for USD. Even in the steam community market the frontside misty is like $15 on the market. I really dont get where you're coming up with the prices.
If you're willing to actually be a bit more reasonably, I'll gladly overpay a little bit in TC/Items
