Spreadshirt is suffering a serious case of poor communication. Yes, customer prices are increasing quite a bit, but Spreadshirt is bringing prices in line with the marketplace, where they have experience knowing how to price things. The price increases only give Spreadshirt more of a share of the product for low volume sales. If you sell lots of items, Spreadshirt's commission model gives you possibly the most generous commission of any POD.

Spreadshirt, existing shop owners can see customer prices increasing dramatically. Until you address this directly, you're leaving people feeling conned, especially because the calculator shows many products increasing in price while also reducing shop owner commission (at low volume).

It would also do you well to fix the illustrations. The one above says that you are keeping prices the same and reducing your share of commissions to increase ours. The reality is that prices are increasing across the board and that Spreadshirt's share only reduces relative to its current share at high volume (and at higher commissions that the 20% shown in the illustration).

Treat your shop owners like partners. Tell them what's going on without trying to hide anything. When we express confusion, fix the documentation. If you want us to invest a portion of our lives building big shops, you need to work hard to show that we can trust the foundation.
