I think a markup that is still a hot deal should be ok, for example a PLAYMOBIL that sold for $2 and I am asking $10 while regular price is $25 should still be acceptable
Nope, while I agree it may be a deal, if you want to profit you can do it in GFST. And people can see it there. If someone requests to pay a markup that's fine.
Otherwise this thread will just fill up with every deal posted for a small markup.
Unless I hear a big demand otherwise from buyers.
