First off, sorry if this is the wrong place to post this. Second, I was just perusing Woozy Moo and noticed they didn't have any Hasbro TF's anymore (though they still have Takara). When did they stop carrying them?

...in other words, it appears you might have missed the Hasbro listings, or perhaps inadvertently filtered them out in a search.
They no longer have Transformers listed in the collector's hut category. You have to actively search for them.
Welllllll... Now I just feel silly. And slightly embarrassed. Thanks for the help with the site, everyone
