What is the customer wallet and how do I add store credit?

Customer wallets come with the Wallet / Store Credit plugin. Once it is on, each customer has a wallet they can spend at checkout.

• Manage wallets on the plugin's page (Customer wallets): give a manual credit or debit with a reason, or freeze a wallet.
• Customers can top up their own wallet.
• Gift-card redemptions are credited to the wallet, and so is any wallet amount on a cancelled or refunded order.

To give credit instead of a cash refund, add a manual credit to the customer's wallet.
