Yes, Italian are spoiled and don't do second hand (I have some frugal friends though, so they swapped baby stuff - I wasn in the UK and totally missed out). I don't miss charity shops that much, I do miss Poundland !
Get the piano, it deosn't matter if the dds will be tone deaf, children love music! (mine did lots of music at their scuola materna, lots of coro, dd is not intonatissima, but loved it!)
