The bit I find odd about US shipping (to Australia at least, I don't know if this is true for other destinations) is that a few years back they removed the cheap, but slow, sea mail option for shipping. Prior to that I could get something posted from the US to Australia at a fairly reasonable price. Yes, it took a long time to arrive (the longest wait was 4 months, but it averaged 2-3 months), but I generally didn't mind waiting if it meant I saved on shipping costs.
Now the shipping times from the US to Australia are super fast, but pretty damn expensive. The best is example I have of how fast the shipping times now is late last year I order the second Walking Dead compilation through Amazon. I ordered it on the Saturday morning Australian time and it arrived at my house on the Tuesday. So 4 days, or 2 business days. That was with the standard Amazon shipping, not express. I've had packages that have been posted from within Australia take longer to arrive than that!
While I love the fast shipping times, I would still prefer the slower, but cheaper sea mail option if it was available.
