That is exactly what buying stuff from China is like. Shipping is "free" but it takes 5 weeks. The ones I ordered came in faster but I just got lucky on the ship.
BTW this comes US mail locally. It is all part of that deal post offices have around the world. The receiving post office has to deliver the package free (or almost free) as long as the postage was paid in the sending country. Most countries whack their shippers pretty hard. China makes it almost free on their end. That is how they can offer free shipping, it is free for them.
I can often buy something (material and shipping), shipped from China and dropped off at the Long Beach post office, cheaper than a USPS package from Long Beach to here costs.
You just can't be in a hurry.
