Shopping channels, I think, are to be avoided. My son-in-law's mother died recently and they had to clear out hundreds (I'm not exaggerating) of boxes containing rings, watches, necklaces etc. They took them to a jewellers who bought them from them, mostly as scrap metal, but the words he said when he bought them were "We get a lot of this, lonely old ladies sitting and watching the shopping channels and buying anything that takes their fancy." The jewellery was still in unopened boxes, never worn. I think this should be a salutary tale for anyone doing the same thing.
