I used to regularly donate to a local charity shop (even volunteered there for a time) but when a new manageress took over she would not allow any clothes which came from supermarkets to be sold - no matter how good a condition they were in - they had to go straight into the "ragging" bag, books had to be pristine, glasses, crockery etc. had to be in complete sets. I think more stuff ended up in the skip than went into the shop. Many volunteers left in protest.
On the other hand I had some laughable experiences when volunteering there, a lady came into the shop and wanted a discount because she was buying 3 things! When sorting through some donated clothes I came across some childrens' dirty underwear (I always wore rubber gloves after that), toys with bits missing, jigsaws with pieces missing (we had to count them).
