If you give them the $1 from your paypal, they will continue to charge you $27 and it's very difficult to get them to stop. I sent them the cancel email about 4 times before calling my bank.
The solution is to log into your paypal account:
Go to settings
Go to payments
Go to Automatic payments
Find the one from JVZOO.com and cancel that one, it will stop them from charging you for access to a website that does nothing at all. Huge waste, major scam.
Hope this helps.
