Any guidelines on eBay purchases?

Hello!

All good points, just a few remarks

This is especially suspicious if the seller has other calculators and electronic stuff on sale or is known to regularly sell those. Sentences like "I couldn't test it because I don't have batteries for it" or "unit is untested" are always equivalent to "the calculator does not work".

As I am more interested in the real old calculators (before 1980) I don't usually mind. These calculators will not have been stored in the open during those four decades. And whether or not they lay in a drawer or box with their case does not make any difference. On the contrary, there are some calculator cases with a foam padding that can turn to sticky crumbles over the years, which are quite difficult to get rid of. The Ti-58/59 series are prone to that. I rather want them without their pouch!
