BestBuy.com, the electronics retailer's Web site, said Tuesday it will offer 99-cent standard shipping on most products, except those that require a scheduled delivery.

The limited-time offer started Monday. The company did not say when the offer will expire. Many retailers are offering discounted shipping around the holidays in an effort to entice customers.

The company also said orders placed by 11 a.m. EST on Dec. 21 will be delivered by Christmas.

Shares of Richfield, Minn.-based Best Buy Co. closed at $43.53, up 70 cents from a day earlier.
