When the little box pops up telling you enter payment, hit the 'X' to get rid of it - if you hit OK, it will keep popping up and annoying the hell out of you. I think free admission only comes with purchasing all workshops.

There are two sections for each item (member and non-member). Just make sure you are selecting the right payment (both prices, pre-July 7 and post July 7, are listed). If you are not a member, then select your entrance from the non-member drop down box, hit the payment button. It will take you to paypal. you will need to click the "continue shopping" button to go back and select your workshop. Hit the payment button and you will be returned to your paypal screen to finish the transaction.

Diana, Patrisha here.
Im on the board of SAMEDA,
Did you get a reply to your question from Meleah yet?
Rachel has agreed to do a second workshop if she sells out the first so there will be room.
Let me know if you still need info
Thanks
