YesAsia has free shipping on orders over like $30 or something but they're kinda sketchy and they take ages so I stopped using them and switched over to CDJapan. They always have cute first press stuff if you're interested in that, they're a bit more expensive but J-Pop releases in general are if you're after the Japan press. You can get pretty good quality second hand stuff for much cheaper on eBay if you're not fussed on stuff like that (mostly older releases tho, stuff from the last few years [around Party Queen until now at least] will still be a bit more than stuff before that).
