This was one of two toys given as a set to our youngest for her third birthday -- the other was a shopping cart.  Her and my son have had a great time with these toys.  Though this is not the most attractive looking cash register on the market, it works WELL.  It comes with a credit card and with fake money that look real.  The door opens nicely when the Open button is pushed.  The cash register calculator works.  My son, who is 6, enjoys using the calculator to play with for numbers.  He'll often add large numbers together just to see the results when they playing shopping together.
