I have an e-commerce business also and have used Shipstation since they were a startup. Good outfit and works well for us. With this said we are also looking into ways to further reduce shipping costs.
Since we also sell on Amazon, I will be looking to see if they open up the Amazon shipping to third parties for shipments that do not originate from Amazon. That is something I understand they will be rolling out this year.
We ship via first class package a lot, that is the majority of our shipments. $100 of insurance and we use a third party for extended insurance if needed. Insurance is no good for international.
Sadly shipping from the USA is never going to be cheap, and with Covid it has only gone up in price. International shipping is very expensive thanks to the WTO and how China has manipulated the postal services via that body. That is why it is cheaper to mail something from China to your neighbor then it would be for you to send the same item from your own house!
Avoid things like Smart Post from FedEx and UPS. They flat out suck. They save a little money, but the shipping is VERY slow. Basically the shipment goes across the country via UPS or FedEx, and final delivery with by via the USPS. But that final mile may take days or weeks! All it does is piss off customers.
I’m keen to hear anything you discover on this subject. We are currently working on add volumetric data on our site to get very accurate shipping quotes for our customers. Problem is we have nearly 4,000 SKUs. They range from tiny to larger the USPS can ship.
I hate to say it, but to get international shipping to a lower number you will need to have the items shipped from outside of the USA. Setup with trusted partners around the world… Yeah, even more to manage.
I would like to add that you did a great job on my full kit from you. Very well packed and well thought out. Nothing missing. Well done!
