Thought you missed out on free shipping? Not so fast! A group of merchants -- albeit a much smaller group than we saw for the Dec. 17 free shipping day -- have banded together to offer free shipping with guaranteed delivery by Dec. 24.

Some of the merchants have a minimum purchase amount, generally $25-$50, to get the free shipping. The deal works as long as you ship to a single address within the continental United States. The free standard shipping will kick in one you add items to your cart.

Visit the Web site of a retailer below and order by Dec. 21 at 11:59 p.m. EST to get the deal. Participating merchants include:

• Aeropostale
• NFL
• Levi's
• Dick's Sporting Goods
• iRobot
• Sports Authority
• Calvin Klein Jeans
• MLB
• Kate Spade
• NBA
• Speedo
• Modell's
• Kenneth Cole
• NHL
• Calvin Klein Underwear
• NASCAR
• Sephora
• Ghirardelli Chocoate

Caveats: not valid for shipments to APO/FPO addresses or previously made purchases.
