Yes, we are monthly now, but you don't have to subscribe at all :) - you can purchase one at a time.
I'm sorry you're still getting errors! Try clearing your cache (cookies and such) and then going directly to www.wantable.co. For some reason we are still having caching problems since our IT guys built the site from scratch. The email links sometimes get messed up with this as well. We know this is a pain, we're working on it, sometimes it's tough being a startup!
Also, if you're having any problems ordering or viewing things, you can shoot us an email anytime.
I apologize guys, we're doing our best over here, and we really appreciate your input!
