i've bought Trigun Perfect Collection (English Dubbed), Escaflowne Tv/movie Perfect Collection, and Initial D - Bundle Special. All of them arrived just fine and only took about a week each.
I think there was another place that had anime for cheaper, but it didnt have any guarantee's if it didnt arrive in the mail. I'll have to ask my brother what that place was, he told me a few weeks ago.
But anyways, I think discountanime is a good place to buy from.
I also havent watched all of excaflowne yet, i'm only on like the 3rd episode.
