LOL Dolls Duplicates

My granddaughter is lol crazy so for her birthday her mum spent £70 on one of the large sets in Smyths toys. One over the moon granddaughter !! However.... she had money from other people and got enough to go and buy another £70 set so off she went to smyths with her mum to buy it. The excitement soon turned to tears when she got home and opened it and it was exactly the same as the one she had been given !! Bearing in mind that there are so many to collect all supposedly different. She was so upset it almost ruined her birthday. I am fuming And she was heart broken.
