How can i let the customer created the coupon by themselves?
I mean:
1. Retail A come to my web site and created a Coupon Code
2. Retail A give the Code to their Client B
3. Client B come to my web site and buy product using the coupon code
4. Retail A earning money from the transaction
If anyone can let me know how to do it or are there any add-on/module to use? Thanks
