For now I only own the first 3 volumes of Tokyopop’s The Masterpiece edition but I’ll grab the rest because it’s Aria (I've also ordered the BD of the first season, still in transit). I’m not a collector and I don’t like physical goods all that much due to them taking up space and needing to be stored properly (I hear UV light damages some media).
That said, I ordered from Amazon because I'm familiar with their international shipping but I’ll look into rightstuff because the GWP postcards look dope lol.
