Effective immediately, credit deposits must be made to pay with Gems (credit deposits can be made while a group buy is in the payment phase). Steam Inventory deposits from accounts created after August 30, 2018 will be assessed an additional 7% fee unless the items purchased directly from the Community Market to deposit (must provide proof).
Mann Co. Supply Crate Keys are now also being accepted on a limited basis.
Gem to USD values can be determined at https://grp.li/ugems.
