i bought this toy for my 3 1/2 year old son and he loves it.  He thinks he is playing but he is also learning math and about money.  I had to take away the change, since we have also have a small one in the house, but the paper money is just as fun to play with.  The only thing that I would change is the paper money.  I wish it was laminated so that our younger son couldn't rip it or crinkle it up. My younger son crinkled up the money and when my older son put it in the register it got stuck behind the drawer and we had to take it apart to get the money so the drawer would shut. other than that, it is huge fun in our house.
