Ugghhh, I hate shipping overseas.
I've sent stuff to Ireland, Europe, one I think to India, Australia, Canada eh, Mexico, and a couple other countries.
I've always had the best experience with Canada, obviously b/c they're closer to us and more reliable ^^.
The rest are a mixed bag, although I've never had any lost packages. The only bummer is knowing you've paid for global priority 4-6 days, but it will take two weeks.
EMS is the way to go if you ever send packages internationally, although a bit pricey.
UPS is also very good when it comes to international, as you can track the packages and know an ETA of delivery.
