The $14.99 Premium subscription rate ended on November 3, 2020, so you might have bought your machine after it had expired.
They do offer a discount occasionally (in December they offered half off with a coupon), so since you missed that one, you could cancel until they offer another special. (Be sure to read Dan’s announcements every month or so. ) You will miss any freebies along the way, but you might not be using the other functions now, and prefer to wait until they add more goodies to the software.
The Premium subscription is going to be a continually growing thing. Be aware that if you cancel your subscription, you are going to lose some functionality that is associated with it…like Text, Shapes, Offset, Stamps and Puzzles, as well as DXF and the free for commercial use designs.
(Or you might not lose DXF, that one might be grandfathered in at a later date. But you will be limited in storage to most recent 30 days worth of files, so check out the discussion threads for the announcements starting with September 2020…that one lists the Premium functions.)
