In Belgium there are shops called "Kringwinkels". You donate your stuff you no longer have a use for, and they sell it again at relatively cheap prices, possibly after some repairs or cleaning up. I guess the concept does exist in many other countries as well.
There are two such stores relatively close-by, so I regularly pop in to see whether they have anything that can be useful for gaming. Last week I bought a wooden block set, priced at 3 euro. Could be a handy additional set for my vintage wooden block set I described earlier.
The brand is VERO, and apparantly was a toy company from former East Germany.
