Will we have the option to buy again if we miss or can't buy during the individual sale month?
We would never say never but we will not have any pre-planned reprints. It will depend on demand, our capabilities at that time and author approval. 

Some of the books we are featuring are part of standalone series and we do have plans to complete some of them at some point the following year. The timing will depend on any exclusivity contracts the authors may currently hold with other boxes, our capabilities for shipping and demand. They will be announced ahead of time.
