Thousands & Thousands of Tiny Robots.

Cheap Shipping

By: Modular Robotics

I’m not a fan of the US Postal Service.  They’re basically bankrupt, they’re bloated, they’re always increasing prices, and they deliver so much junk to me that I feel guilty for cutting down the rainforest every time I check my PO Box.  They’re always losing my mail too.  But, they’re cheap.  A lot cheaper than UPS for international Cubelets shipments, and a little bit cheaper than UPS for domestic shipments.  We just added a couple of USPS shipping options to the site, so if you’re in Japan or Finland, we can now ship your Cubelets to you for $40 instead of $140.
