Bought it during promotion and saved a cup of coffee☕️money. It is convenient to charge. After charging, it will be in the account. You can buy it at any time and use it at any time. There is no expiration date, but it will not stay in the account for long. I think it's still very convenient, and you can save as much as you can. For friends who often buy hands, you can take a look and add a few more. This is money when it is charged to the account, and it can also be used to offset the shipping fee (points cannot offset the shipping fee)
