I checked walmart, kmart and other stores no one sells calculators anymore. Ebay has a few but not what I want and they seem over priced. Online calculator works but I need a calculator for my shirt pocket. I had 2 nice calculators 1 died the other vanished. I need a solar charge calculator sometime handy easy to use at the desk and work bench.
Where to buy a good low price solar calculator?
