Not sure why you don't want to leave your items at a Tempke so not sure if my idea will fit.
I have never seen a charity outlet. Charities exist but I believe they are mainly affiliated to international organisations, such as UNICEF.
I was going to suggest, seeing as you appear to be in a rather remote area, going to a local school. Out in the sticks there are many small schools serving one or two villages. The kids there would be grateful.
