I think it is a shame that they don't accept second hand toys any more. I can understand the reasons, particularly as some people will donate any old thing they want to get rid of.
Also, to be fair, people might be blinded by their love of an old toy they or their children adored once, but is now not as pretty as it used to be.
But, there are plenty of toys out there that get played with once and then get thrown out.
If you have any decent toys like that, consider giving them to a second hand toy shop... at least some child might be able to get them cheap, if not free.
