We bought the cash register for my daughter for her birthday, which is still a couple months away.  Therefore, we are unsure  of the durability of the product.  I did take it out of the box when it arrived to check it out.  It does come with play money including both paper and coins.  It is solar powered and actually does math. It comes with a credit/debit card that can be swiped.  The thing I like best about the cash register is that my daughter will be able to use it for many years.  It is usable for a 3 year old and will still be much fun for an 8 year old.  It seems to be the educational toy I was looking for that will grow with my daughter.
