Some charity shops do ask too much for their clothes, I have seen Primark clothes priced higher than their original price!  .

 I love shopping in charity shops because you don't know what you are going to find.  It's not a matter of "needing" to shop in them for most customers I know, just a wish to find something you won't find elsewhere.  Yes, people are picky, and quite right, you have to like what you wear. True, there are shops in the High Street where you can get cheaper new clothes; but I'd rather find a better quality garment that might normally be out of my reach.  

I too worry about clothes being binned after people have taken the trouble to put them in a bag and deliver them to the shop rather than put them out with the recycling, and donate to shops where I feel there is less chance of waste.
