A merchant can create a credit and give it to the customer. The customer can then redeem the credit by entering the credit code in the checkout process.
All credit information appears in the vendor's order retrieval form.
Before a merchant can give out a store credit, a credit number must be created. The screen will refresh and a line will be added to the textarea below. There is one credit per line and 4 parts to the credit. This number will never change with time. It is based on the number of days since the certificate was created.
