Hi, I'm not sure if this is the right section I'll try anyway.
What are the best couriers you used in your experience for delivering your Boardgame products?
I'm talking about a pretty standard 3-4 kg box shipment to U.S.A and EU users for our small Kickstarter project.
Thanks in advance
If you're talking about a small project, you're best off using USPS - it's simple, inexpensive, fast, and reliable.
However, if you're trying to ship to international customers without them being charged customs fees at the door, that's trickier. For that, you'll need a warehousing and fulfillment service from within the region. Companies that can help with that include Shipwire and Ideaspatcher. Please note: if you go with this, your business process complexity will go way up, but international customers will appreciate your effort.
