Check out Asendia. They are doing consolidated shipments which might work out nicely with this.
Works basically like this:
You collect couple of shipments to one bigger package.
Then you send that bigger package to Asendia logistics centre and they will send those individual packages to users.
This is great! Thanks for creating this - and as someone asked already, I would love to hear more about the process how you did this. Especially I am interested how you came up with injection molded enclosure (I thought it just costs some enormous amount to make the mold).
I was about to order but frankly it does not feel good to pay about the same amount of shipping (to Finland) as the product costs.
If you can do anything about it, I would be happy to order. 90EUR for shipping is just too much, 20-30'ish would be reasonable.
Otherwise, that is my observation also.
