Yes, I tried a bunch and I swear by Printful. Great products, great working integrations, and they have several fulfillment centers around the globe to fulfill orders worldwide quickly and with the lowest shipping and other charges possible. Now also a new fulfillment center in Canada. This means that I design in Slovenia, and upload items to an international marketplace like Etsy or Storenvy. When a Canadian customer buys the item, it's made and shipped in Canada (no import charges, low shipping cost). Love it and love my Canadian customers.
Printful offers lots of integrations for different sites and marketplaces. Integrations work so well, so easy to use. Just love it. No subscription fee to use it. And lots of sustainable items are available and they keep adding fashion pieces made from recycled materials. This is really important to me, as I want to offer sustainable fashion to my customers as much as possible at the moment.
I can also be integrated with uCraft, the website provider, I made this website on. My future plan is to also have a shop on this www address, not only as part of other marketplaces.
The recycled tracksuit is one of my favorites.
Currently 20% discount on the site.
