seems like a good deal to join and cancel.
cheapest membership fee found on site was the $16 monthly fee package.
it's limited to the first 1000 members though and I'm not sure how long it takes them to send out the voucher.
anyway, thought I'd share since it's $16 for a $50 voucher is pretty good particularly if you plan on joining already.
