The Source have this BIOS dual ear/forehead thermometer on sale for only $9.96.  As with most deals from The Source, they likely have very limited online stock (no stores near me have this in stock).

The large illuminated LCD display is easy to read and its compact design makes it easy to store in bag, purse, or medicine cabinet, with a handy storage bag for safekeeping. The thermometer also features an automatic shutoff function and fever alarm with fever glow technology that displays color when fever temperature is reached.
