Everything is paid from your balance; there is nothing to pay at checkout. The price shown next to a number or a package is what you pay: it does not change after you press Buy.
- A number: the price is set aside when you order and charged only when the code arrives. No code, or you cancel first, and the amount returns to your balance on its own.
- A proxy package: the price is charged when the package is delivered to your account. If it cannot be delivered, nothing is charged.
Funds never expire. They are not refundable and cannot be withdrawn, as the Refund Policy describes.
