This is interesting! It will definitely take some fiddling around with to get the options right and commission per item back to normal for my shops. The price of designs on the market will go up drastically since you will need to increase design price in order to keep profits the same. That being said, you can always upload one design with a higher price for your own shop and one design for the market for other folks to use. Perhaps I could make this work to my best interests but it seems that Spreadshirt is just doing what is advantageous for them. I'll have to take a closer look at the math once it is finalized and in effect.
