Yeah, I'm glad US Customs isn't so bad with packages.
Of course there's still the whole waiting for a package to actually get through customs *stares at one that's been there since Monday*
I can only remember one instance where I've ever had a problem with customs. Had ordered a dakimakura cover from the folks over at Evening Call, and while I love the fact that they ship internationally and allow you to pay via PayPal, their responsiveness is shit. The cover was slated for release in early December, and I got notification that all of them had shipped in Japan, but no tracking number for my EMS'ed cover. Few weeks went by, and nothing, so I tried to contact their support for tracking, but still no response.
Then one day, out of nowhere, a package showed up from Japan containing my cover. Took the tracking number, went and checked it out online. Turns out it'd been in US customs from somewhere like January 2nd to January 23rd. Terrible for an EMS package that'd usually get clearance in like two days.
