Burger King's website says it is offering free "satisfries" on Saturday and Sunday, hoping to drum up interest in its new lower-calorie french fries.

The fries have 30 percent less fat and 20 percent fewer calories than regular fries, Burger King said.

The chain said it expects to give away 10 million value-size orders of the healthier fries, which sell for about $1.29.

 No coupon is required, and no purchase is required. Customers can get the offer by asking for free fries at the register.
