Donate, donate, trying to get more money to buy items to donate...
But seriously, I think that it would be cool for you to have kind of a "trade in feature", like if they want for example Camo Sec. Gradient, but they actually want to keep it, and they don't have any money to buy it, and say like they have like Sphinx or Pharos, they could trade their Pharos or Sphinx or that whatever item they have for that Camo Gradient.
But, the item that they are willing to offer for a trade MUST BE AT EQUAL OR GREATER VALUE.
So I cant trade like, 30 Orc User Texts for Demon Blood or something.
