In my country, the day after Thanksgiving is a day for lower prices on goods in various stores. It is called "Black Friday" because stores whose profits have been "in the red" (losses) finally make enough sales to be "in the black" (gains).
There are a couple Black Friday deals that I thought you may be interested in. Here they are:
Rachel Heffington's book, Anon, Sir, Anon, will be 25% off in paperback form on Black Friday. Here is the link to her post that tells about it: My Sister Gets to Keep Her Cat.
Elizabeth Ender's book, Ransomed, will be about 30% off on createspace on Black Friday, if you use her special code. Here is the link to a post telling more about it: In Which I Try to Sell You Cool Stuff.
