NOTE: There is currently a bug with the skin store where players are receiving this error message when purchasing a bundle or skin, even when they have the correct amount of Rust Coins in their account. We are aware of the issue and are working to resolve it, please be patient.
You will receive this error message when you try and purchase a skin without the correct number of Rust Coins in your account. To purchase skins from the skin store, you need to first have Rust Coins in your balance, which can be purchased from your respective platform stores through their website, on your console, or through the in-game skin store by clicking the BUY RC button.
