Regardless of which eBook device or app you use or which store you purchase from, BookBub can help you obtain books at discount prices or even free. BookBub doesn’t sell books themselves. They just “simply alert you by email to fantastic limited-time offers that become available on retailers like Amazon’s Kindle store, Barnes & Noble’s Nook store, Apple’s iBookstore, and others. Book publishers offer deals at these sites for promotional purposes, and our staff works with them to determine the best ones to feature to our members.” Joining BookBub is free; you just sign up for a free daily email. You specify the genres you’re interested in, and BookBub does the rest. They send a daily email featuring the best “ebooks ranging from top-tier publishers to critically acclaimed independent authors” that will interest you. Sign up at BookBub and start building your library and discovering new authors and free or reduced-price books.
