Affiliate commissions will be paid on ALL products purchased from the CafePress Marketplace through your Affiliate program links. Affiliate commissions will NOT be paid on products purchased directly from CafePress shops. To receive affiliate commission on products, the link you establish must go to a product on the CafePress Marketplace product page.
For example, this links to a product within a CafePress Shop and will NOT receive affiliate commissions: https://www.cafepress.com/garfield.782343036
This link goes to the same product in the CafePress Marketplace and WILL receive affiliate commissions:
As a CafePress member with a shop, you can get affiliate commissions by linking to your own products IF you link to your products within the CafePress Marketplace. You cannot receive commissions for linking to products within your shop or any other shop.
If you would like to include your products in the CafePress Marketplace in order to link to them and receive affiliate commissions, you may do so by clicking on "Edit Shop Profile" in your account and unchecking the box for the field "Marketplace, Affiliate, and Shopping Channels Opt-out". If the box is already unchecked, your products are already opted in to the marketplace. To edit your settings, go to your store settings page: Your Account > Your Shops > [Shop ID] > Shop Profile.
