Call it Spring Fever, May Madness or just plain crazy but for the next few days only, if you sign up for a class you will also be credited with the full cost of that class and can apply it to a future class (or classes).
For example if you sign up for the 'Do it with Feeling" weekend workshop and pay $425 you will not only get to attend the class but will also have $425 to spend on other events and workshops. (excludes events that take place outside of the US and excludes ones that require overnight stay).
You could sign up for the Body-scapes class on Friday May 23 and then attend the outdoor portrait shoot in Hull for free and still have $75 to spend on future events.
Enroll you teens (or someone else's) in the summer camp in July and get $500 worth of workshops for yourself .
Just go to the page for the event you wish to attend and sign up in the usual way. You will automatically credited with the full amount you paid to be used for your own choice of future workshops.
If you don't see anything that interests you don't worry - you can sign up here and pay any amount and it will be doubled- e.g. pay $100 now and get $200 in credit. Just RSVP here and edit the amount when you get to the PayPal page to be whatever you like from as little as $10 to as much as you like.
