Awesome,

I remember liking Doherty's Brother Athelstan mysteries which I got during a long-ago Severn House sale, and just scooped up all the 99 cent ones now (less those that were already in the 3 money-saving omnibuses at the same price and the one that was a freebie giveaway years ago), and I'll likely get some of the $2.99 fills for the series I'm most interested in trying first (mostly the Ancient Rome/Greece/Egypt ones).
In case anyone else is wondering what fits where, and how much you'd need to fill from the higher tiers afterwards, here are the 99 cent ones (thanks to
SYKM and
Wikipedia), which also have some non-fiction and non-mystery historicals among them:
