I missed the last Black Friday sale, but I think I still have around 50 credits. Planning to grab another hundred if we get a Black Friday/Cyber Monday premium sale this year.
I'm one of those readers that prefers to read everything in one go...which is the polar opposite of the weekly chapter release method. I generally try new stuff out when it's on a catch-up, and if I like it then I buy the series up to current and pre-order as new volumes get added. Then when I have the itch to read a particular series I jam the whole thing out (yay for cardio machines) through the current release. And yes that does mean I end up re-reading earlier books, but I also read through those faster (refreshes my memory on the entire story) before I take my time with the ones I haven't read yet. The bigger series like Smartphone (last read through was after volume 19 was released) I may end up waiting until it is fully finished before I read again (as long as the author doesn't pull an unintentional Robert Jordan).
And I'm so glad JNC self publishes electronically - getting real tired of Amazon's Kindle division that is human understaffed and badly managed by some junkyard pre-alpha version of Alexa's AI.
