No Stock - Misleading Advertising

My 9 year old son read the National Geographic Kids edition a few weeks ago where he saw an advert of the release of some new dinosaur figurines, advertised exclusively for Toys R Us and being released on 25 October 2015 - today. After quite a long wait and numerous requests during the period not to forget to take him on the day, the day arrived. However when getting to Toy R Us early as stocks may have been limited, we were told that had not received any new stock.<br> <br> I was told that they don't receive stock on Sundays, which is fair enough, but then don't advertise that the stock will be available on a Sunday. <br> <br> Are toys stores not supposed to make children happy. Not disappoint them.
