For those fretting over missing out, I would actually use DS.com's search feature for the pin you might be looking for. I just found the entire Monument series from June 2010, all in stock and addable to your carts. Only the Mickey one was on sale, but it had the Tinker Bell, Scrooge, Chip & Dale, and Stitch (though no Jiminy)
Funny thing is, they are not showing up in the Pin category when you browse it, you have to do a keyword search.
