It was free for people who had downloaded the beta version - they had a coupon added to their accounts (shows up on the screen before checkout, and on the checkout screen itself). Chippsyann, if you downloaded D|S before version 1.0 you may find the coupon ist still active and you can get DForm for free - try putting DForm in your basket and go to checkout, if there's no coupon option go back to your basket and remove the item, otherwise claim the coupon and carry on.
