If you are in the United States from May 28 - May 31, you could go to a Toys R Us store and buy two Barbies and get one FREE Barbie, if the dolls cost $19.99 or less. The sale is also online at www.toysrus.com. If you live outside the United States, you can check to see if Toys R Us will allow you to buy from that website.
Fashionista body fans, time to shop!
Good luck getting those less expensive doll or dolls.
