Walmart, Toys R Us price war could forecast a harsh holiday in Toyland

In yet another sign that this year's holiday season will be fought hard in the toy aisles, both Walmart Stores (WMT) and Toys "R" Us announced expanded promotions for holiday shopping.

Walmart will cut prices on another hundred toys, including more additions to its 100-toys-under-$10 lineup. It cut the prices of popular board games like Candyland and Yahtzee to $5, and marked down popular toys, including the Bakugan starter pack (now $8) and Star Wars light-sabre (now $15). The retailer also announced it will offer free shipping on all online toy orders picked up in-store, including bikes and scooters.
