Anime-Export as previously mentioned.
they were pretty good when I used them. I ordered Fort Max, Animated Version Reissue Devastator and a couple other items from them. it all came nicely wrapped in bubble wrap but there was a bit of air in the box which would not have provided much support if treated too roughly.
While they require up front payment they do not charge for shipping until the item is packed and ready to ship. by default they use the cheapest shipping method.
my biggest gripe was they contacted me prior to shipping to say that they didn't have the Alternity Thundercracker that I ordered, I got a refund that effectively went towards shipping. I later contacted them and asked why it was still listed as in stock on their site. they said they would fix it.
it's now a year later and they still list it as in stock. I honestly think they couldn't get it to fit in the box so they left it out. rather than find a larger box and spending more on packing.
I double ordered G2 Sideswipe and Wheeljack through them on Monday. they should both ship together in August.
I'm pretty excited about this wheeljack, like everyone else I'm a little bit worried by the apparent nuber of joints on the chest/roof.
