When you sync your Etsy store with Printful, all flat shipping rates for all product categories are automatically pushed to your store.
If you’re creating or syncing products manually, you need to select the right product category for shipping. Go to your store → Listings → Shipping → select the shipping category.
Etsy also applies a 6.5% transaction fee on all orders.
Live shipping rates are not available on Etsy.
