Will I get my order in one shipment?
No, not always. Printful may split an order into multiple shipments for the following reasons:
1) Product packaging. Some of their products are individually packaged to ensure their shape and provide extra cushion and durability. The products they will always ship separately are mugs, wall art, stickers, jewelry, bean bags, backpacks, pillows with stuffing, and snapback hats.
2) Fulfillment location. In their Product catalog, you'll see that they fulfill products in multiple locations (e.g., US, EU, AU), so if your order consists of products that have different fulfillment locations, they will ship the products separately. Shipping costs for orders with multiple shipments will be higher than for orders with a single shipment. See the final shipping costs in the order checkout.
Will I get charged for customs?
Import duties and taxes are not included in the item price or shipping cost. If your order's shipped from a facility that's in a different region than your delivery destination, you might have to pay handling and/or customs fees upon delivery. The customs fees may vary depending on the order value, country limits, etc. If you live in an EU country, there should be no extra expenses, but I can not guarantee it.
Do shipping prices change based on product fulfillment locations?
No, the shipping rates are not impacted by the location where the products are fulfilled. For example, it'll cost the same to ship a t-shirt from the US to Germany as it would be to ship the same t-shirt from the EU.
