BoB is having a father's day sale that includes 30% off thrillers and sci-fi, and 25% off new releases and mystery novels.
Also, BoB now does the same thing as Fictionwise, where they always have 100% Rewards (same as micropay) books available (so essentially, the books are free). The selection seems to change frequently, so it's worth checking back every week or so to see if there's anything interesting.
Happy almost-Father's Day dads
