Selling Cards to a Customer Account

Selling Cards to a Customer Account
 * Some customers who buy cards from the card POS want to use store credit to do so. There is a special procedure that we use to do this for them!
 * Next to the customer's name is a button that says "account balance". Click the number that is highlited.
 * Put a "-" next to it, followed by the amount of the cards PLUS TAX.
 * For the reason, put Trade.
 * That will bring you back to the main screen. Click "apply discount"
 * Enter the full amount of the cards only, WITHOUT tax.
 * For the reason, put Trade.
 * Hit "cash" for the sell mode, and the total should be $0.00
 * Important to include the reasons of trade, and make sure to double check totals with tax or without.
