I checked my preorder last night, because I had the shipping to go to my "old" job. So, I was relieved it hadn't been sent. It said that I was slated for shipping on Sept. 5-10. Which is in keeping with Miss Winthrop's info at least. I will keep my preorder status and lets see if I get it at same time as those who just ordered it.
Interesting note, I am a huge Costco addict. I had a certificate for $20 on their web site and used it for a movie that I didn't realize wasn't yet released at the time. Another time I pre-purchased in the store itself. One I got a day early or the day it was released, the other I got SEVERAL days early. Of course, they don't handle a huge selection and I have not seen the DS collection there. (They do have Buffy season II in the stores, not sure about the web site.) Anyway, just thought I would mention how they compare. Perhaps that isn't fair to Amazon though, if the actual problem is with MPI.
