It's easy! Tell your friends about the OKC Ski Club and ask them to become members. They in turn write your name on the membership application and you get $25.00 off the ski trip of your choice per each new member!
Only rules: 1)They must not of been members for the past two years. And we know who that is. 2) Certificates must be used this current ski season. 3) Certificates are non-transferable.
And there is no limit to the number of certificates earned, thus the reason you can earn a free trip!
Here's a quick link to the membership application. Or have them do it online, it's faster and easier. Either way, you'll still get credit.
