PRINTFUL Addon: Add more items (stickers) and sync Printful shipping
1. Connect stickers from Printful to the Printful Addon with Lumise. Add all accessories such as signs, backpacks, etc.
2. Synchronize the Printful shipping rates. Printful already synchronizes their rates with the Printful plugin so this should be possible.
3. As soon as the Printful Addon is activated, all Printful products should be immediately available to activate as a Product Base when launching the design editor. Users can activate and deactivate Printful products from Lumise in the WordPress dashboard.
