Here's a little bright spot. I have bought a couple sewing patterns from seller Noahslady in British Columbia. On both occasions, they got here well within two weeks and maybe one week (can't remember), and as I recall, I didn't pay exorbitant shipping. I hope she didn't have to eat some underestimated, surprise postage!
mapquest.com told me the trip is 2320 miles, so I think that was pretty good speed and cost for being international.
