For the 2 years, my 4 year old has been pestering me to buy him a cash register. He received 2 other cash registers during his birthday and Christmas. We had no idea that the one that he has been talking about these past few years was the Teaching Cash Register. We never understood why he never seemed into the ones that he had and would still ask about when he would receive one. We thought that it was a case of the gimmee gimmees. While at a friends house, he saw this particular model and started to exclaim, "Mommy, Mommy! This is the one that I've been talking about!" After a lot of careful research and talking it over with my husband, we decided to buy it for him. we also did alot of price comparisons and found that Overstock had the best price. Though this item is a bit pricey, it is worth very penny. It does teach math skills andit does teach them about money. He has been playing with this every day!
