What the heck is up with MakerShed's shipping rates?
I've never ordered anything from them, but unless they've got enough volume to warrant a whole shipping department (which I doubt; they're hardly DigiKey
), they probably box everything onesie-twosie by hand & then maybe call in a UPS pickup.
That said, it does sound a bit spendy, especially if the weight & size were relatively low & you weren't requesting express shipping. Might want to check out Noise's links.
