How do I handle special online discounts, coupons, and Promotion codes (Promos) like Groupon, Living Social, CertifiKids, etc, online?

While coupons, promo codes, etc.  cannot be automatically applied during online registration, you can utilize a few Jackrabbit features to get the job done!

Add Coupons/Codes to Online Web Registration

Go to Tools menu > Edit Settings > User-defined Fields, label a Family User-Defined field as "Enter Coupon#". This will provide a text box on the Registration Form where the customer can enter the information.  

Post a Credit for the Promotion

Follow the procedures outlined in Post a Credit - Groupon Credit Example to apply the credit to the account.
