Charity shops are a great place to pick up interesting wool. But they have to charge less so people buy it, when you think about it if it is only the odd ball or 2 probably people will only buy them for snoods, hats or suchlike, to make a top you'd probably need more, and probably that makes/colour is no longer available. Super if you can get enough for a bigger project.
I got a knitting bag with a lovely skein of Sean weight wool recently, I got to the till and it was half price, it had been there so long that they wanted the room. Not sure what to do with it mind but maybe some gloves and matching hat Also got some super chunky wool recently and am having fun with that
I sometimes buy books from Oxfam online, when having a browse recently for books about my interest I found several copies of a book I'd love to have but always too expensive. 2 of the copies were very expensive indeed, it's out of print, a short publication run, but the 3rd wasn't. Half the price of one and a third of the price of the other. Still a bit dearer, but not much dearer than had I been able to buy new. I bought it, it is immaculate, it has a protective cover on it, and it looks like it's been read once .
The dear ones several weeks later, still there, £120 and £70. And another copy for £150! The £120 copy sounds to be in worse shape than mine.
Oxfam now have the cost of the copy I have to help fulfil their mission, but the other 3 copies are sitting on shelves
Things are only worth what people are willing to pay for them. I've not felt bad about buying a lovely coat at half price on the label price at the end of the season, as someone else would have, and had it not sold would they have sent it for rags or would they have had to store until next autumn. I did resonate the one that it replaced but to a different shop, sometimes that's all that is needed
I've never found a mung vase or unknown to them gold or diamond jewellery, they do have it in my local one and they sell it for a high price.
