They just went live on Greenlight give them a Upvote 
This must cost a lot… But really awesome.
Current pricing options direct from the company are:
MONTHLY SUBSCRIPTION $ 59.99 Billed monthly
ANNUAL SUBSCRIPTION $ 360.00 Billed annually
PERPETUAL $ 550.00 One-time Fee
If you’re doing clothing design, its truly fantastic, and fairly intuitive.

Maybe they are going with a lower cost pricing model?
I am unsure at this point but they got my interest
