Well, I have been checking amazon in the morning when I get to work, around 8am est pretty regularly over the last month. Tuesday, 9/14 it was up, but I did not get my order placed before they were out again... was pissed! So, checked again, 9/15 around 8:15am est, and they were back in stock. This time I got a set, and looks like they sold out in around 15 minutes.
Anyway, my point, they are still stocking toy shop on amazon. There is an app I was about to install (think it is called buyitlater), but did I not have the correct version for firefox. The app will email you or send you text/tweet you when something is back in stock on amazon. This app is specifically made for amazon, and adds a button to the product pages so you can set up an alert. This might be a good option for those who are tired of checking a page all the time.
