My last purchase was buying some Harry Potter themed Lego's. I now have all the Harry Potter Lego's (once they all come it, just ordered them last Friday). I collect Harry Potter stuff. Plus, my nephew will have something to play with if he ever gets to come over.
My last purchase online was anime. I ordered Akira, The entire series of Ghost in the Shell, and all 3 seasons of Attack on Titan. All of these I bought on Blu Ray. Lets just say, it's the most I've ordered online in a very long time.
