We have a very easygoing refund and cancellation policy. If you upgrade and then cancel within the first month, you will get a full refund.
If you want to try the membership, you can upgrade, try out the product, and if for any reason you don't like it, you can cancel and get
a refund (immediate for Paypal payments, 5-7 business days for credit cards).
Effectively, that's a free trial.
