FatWatch’s regular price is $9.99. At the moment, it is on sale for $4.99 (50% off). The sale will end when the next update to FatWatch is available. (Hopefully that will be soon, but unfortunately I have to divide my time between FatWatch and some other projects I am working on.)
In other words, I do not intend to play games with the price just for the sake of getting on a top 100 sellers list. I’d much rather be part of a top 10 ranked by quality than by volume.
