Paying and your balance
Prices are in US dollars. Pay from your balance or with a card. A card payment adds the money to your balance first, then the purchase is paid from your balance.

Total before you pay
Before you pay you see the price, any discount, tax for your address and the total. The total holds for 10 minutes. If anything changes, you see a new total and confirm again.
Adding money
You can add $5.00 to $5,000.00 at a time. Adding money doesn't buy anything by itself; you confirm the purchase after.
Money you add stays in your balance even if you don't finish buying. It doesn't expire and can't be moved to another account.
Card payments go through our payment partner. Your bank may ask you to approve the charge. Your receipt shows which card paid.
Your balance and your compute balance
Your balance is only for store items. Your compute balance pays for running apps on Thumper compute. They are separate: your compute balance can't pay for store items, and your balance can't move to compute.
Both are in Settings › Billing and balance.
