Can I add money to my account for future purchases?
Yes! You can use what is called the "Credit Wallet" to handle this. Your "Credit Wallet" will allow you to add additional funds to your account to handle future purchases. To access this area, you can either click on the "Account" dropdown and select "Credits" (you will also see your current balance next to this item) or click on "Credits" on the Account Dashboard in the right-hand sidebar.
Notice: In order to use the funds you've deposited into your "Credit Wallet" the value must exceed the cost of the item your purchasing. You cannot use your credit balance to partially pay for an item.
