Adds additional coupon options, including restrictions for new customers, existing customers, user roles, countries and zip codes. The new customer coupon restriction is perfect for e-commerce sites that have a high lifetime customer value. Providing a discount on the first sale can help bring in new customers, without sacrificing margins for those who already love it.

If a customer is logged in, the extension will verify that they haven’t purchased anything from the site before allowing the coupon to be applied. For customers that aren’t logged in, the coupon verification runs right before checkout once the e-mail address has been entered.
