J. Daniels included preorder links in her cover reveal post for Bad for You, linking directly to each retailer product page: (buildbookbuzz.com)
There are preorder links open for such places as Amazon.jp (which ships outside of Japan). (segalization.com)
It's weird because the preorder link was sent out around July 12th and normally it takes MONTHS for those items to appear for general sale. (effortlesslywithroxy.com)
