Please see below for solutions on how to get your Coupon to work:
1) Make sure there are no spaces left over in your code. Sometimes people will cut and paste a code, leaving a space either before or after the code. This will cause it to be invalid. We recommend manually typing your coupon code.
2) Some coupon codes are only good for one registrant. With these codes, make sure that you are only registering one person on a single transaction.
3) If you purchased a Groupon deal, you will need to redeem your Groupon revealing the Coupon code.
