Book view café is having a 50% off sale of selected books until July 28
http://bookviewcafe.com/bookstore/category/bvc-sale/
You choose DRM free epub or mobi and the discount is applied at the checkout.
Unfortunately the books are listed by title in the sale rather than author so there are four pages to search through.
