No much, except the price. The lower price if for those who are willing to subscribe to our annual recurring payment. But, with that said you can cancel your membership before your year is up, if you choose.
But, we're always adding value, so we think you'll love it and you'll want to stay :)
The $97/year offer is definitely the better deal.
Some people still prefer a one-time payment with no stubscription, and if that's you, then that option is available for a higher price.
