Apparently, Fictionwise is having a 20% off all ebooks sale this weekend.
FICTIONWISE WEEKEND: RARE 20% OFF COUPON '043010'!
We don't do this very often, so take advantage of 20% OFF ALL your eBooks this weekend with a 20% OFF coupon. To save, use coupon code: '043010' during the checkout process.
I also noticed that My Bookstore and More (MBaM) is still giving a 20% discount if you use the code word "shinynew"
