I think what also gets confusing, at least for the category lines, is there is:
- a street date for the print version depending upon which line it is
- the ebook date (the first of the month)
- the fact that the titles go on sale on their website one month early
The MIRA and HQN titles don't release early on their site. Often you have to wait for the first of the next month to buy the digital edition if the book releases in print the last Tuesday of the month.
They are getting better about it, but it's not always a sure thing.
I wish we could do pre-orders from them.
