I have a used "Refrigeration Basics III" cd/dvd for sale= $100 includes S&H, some of the graphics like the answer boxes are faded but brighten right up when you click on them, otherwise, the cd works great and I'll include some notes I have. I also have the TECH method book for $30, it has a lot of highlighting but is in good shape. I will hold on to the items until a check clears, then I'll mail them or I can take a money order. trying to make some money. E-mail in my profile, THANKS mentin TECH method or Refrigeration basics III in the subject liine.
