Fridge thermometer

On Ebay are digital thermometers for under $2 with free shipping. How do they do that? I ordered one and The Canada Post lady delivered it to the door.

Anyway, it is perfect for older 3way fridges. There is a hole on the back of the fridge where the copper temperature control lines go into the fridge.

It is easy to pop the sensor through that hole ( re seal it with some calking), and voila you have a constant readout of fridge temperature. The module has an internal battery (two LR44 button cells included), and those cells last years.
" Is the beer cold?........Yes, it is 4.2C!".
I figure the pay down period for this mod is about 10 minutes.
