I'm working on updating my subscribestar page to make it more enticing for people, and the first step in doing so is offering a commission incentive. Though my commissions are limited, if you are an active subscriber, you will receive a 5% discount on any commissions. This is in addition to the already 5% discount for those who commission me to write things involving my characters/world.
In addition, I've created a new tier that gives a FURTHER 5% discount, for a maximum of 15% discount if the story is based in my world with my characters. This tier is $30 a month and limited to the first five people who pick it up.
