I have a Magento 1.9 Store. I want to sell coupon codes as a product name "USD 1000 coupon code". So Customer buy this product then send the order email. This email consist with a unique coupon code which has 1000 USD discount.
This coupon code unique, 1 time use, per customer.
If customer buy 2 qty then send 2 unique coupon codes.
Please help me to sort out this. Appreciate your help.
