If your grand plan for holiday shopping this year is to get everyone on your list Cubs memorabilia, the FBI is warning you to do some research before you buy. If it seems too cool to be that cheap, it probably isn't the real deal.

Every store I have walked into lately has some sort of Cubs World Series Champions merchandise for sale. Apparel and trinkets are usually o.k. to buy from anywhere, but you need to be careful when in the market for things like player autographs and game jerseys.
