Yeah, that site's dates aren't dependable at all. In Nov, some of the first orders were processed and said to have mailed out the first week, and to allow 7-10 days. They didn't arrive for about a month.
So just because it's 10 days later, on the date of shipping according to the site, doesn't mean they're not coming. They're just about 3 times slower actually getting here than advertised to be.
