If planning a summer clearout of the home...
Oxfam Ireland are running a free initiative, you can request a post bag and either send it to them via Post Office or request collection from doorstep.
I haven't had any problems donating books to several (c. 5-6) charity shops in my area and Dublin city centre. Children's soft toys are generally not accepted. And some don't take any toys. And Oxfam in Francis Street is the only place that I know of that accepts electrical goods (in working order or easily repairable).
