Every refund on CubieMart is paid into your wallet balance. That is true whether you cancelled a late line yourself, whether a case was decided in your favour, or whether our team issued the refund directly.
It arrives immediately, it never expires, and you can spend it on any listing. Your wallet page shows the refund as its own line in the transaction history, with the order number on it.
A refund also releases the stock back to the seller and reverses anything they had earned on that line.
