Black Friday seems to be a prime time to find sale prices on Barbie products. In addition to the Barbie DreamHouse, there are also Barbie dolls, cars, and other accessories. Although the day after Thanksgiving has traditionally been a popular day for Barbie-related savings, it is possible to find deals throughout the year. To do this most effectively, you may want to check the weekly ads from various retailers and sign up for sale alerts.
