Cemetary Dance currently has a 44% off code, good on multiple items. I titled this thread somewhat in error, as it will work on other merchandise purchased at their store.
It is: 44JULY4TH
This appears to work on multiple items, including pre-orders, magazine subscriptions, etc. The 44% discount does not apply to shipping.
Here's the link to the full deal description,
http://www.cemeterydance.com/extras/.../breakingnews/
"save 44% off everything in our online store this week: Limited Editions, Lettered Editions, Trade Editions, eBooks, magazines, comics, slipcases, DJs, artwork, other items, preorders, in-stock titles, and even forthcoming and in-stock books from other publishers qualify!"
Their full description does say it applies to ebooks, but when I tested their code on an ebook in Kobo, it didn't work, and when following their book links to amazon or Nook there's nowhere to enter it before purchasing. As they only sell ebooks through partner sites, I'm not sure how one would get the coupon to work.
This coupon expires at midnight on Friday, July 6, 2012
