Hardly raking it in, T, but there have been enough sales (128 copies so far) to spur me on to put out some more volumes. (Of the modest royalties I earn, a big chunk goes to Uncle Sam, in the form of a 30% withholding tax. Just doing my bit to pay off the US national debt...)
Sales of the books increased in December, which I assumed was due to Christmas. For some reason sales were fairly high in January as well.
