I got an email from Kobo today, for $2.00 off some specific books for Father's Day. There are 18 books on the list. The code is 2fordad. I don't know if it's a one time only code or not but I picked up one book that I've been thinking about.
Lee Child's latest Jack Reacher book is listed at $9.99 so you'd get it for $7.99.
