The $1000 paperback

My novel, COYOTE WINDS, will be released in March. A pre-publication/review copy showed up as a used book on Amazon ... at a starting price of $295. The price jumped up several times a day, in odd increments, until it topped $1000. Is this a bizarre market bubble? A computer program gone amok? 

For those of you willing to wait until March, the book will be available for a much more reasonable price.
