On CNBC's MAD MONEY tonight, host Jim Cramer looked at ways to play Christmas -- but it's too late to play. You want the behind the scenes stocks. Out of of these he likes GSI Commerce, Inc. (NASDAQ:GSIC) as the e-commerce nuts and bolts. He says not to buy it now. GSIC can outsource the entire web store and design for you. They serve many large companies. Cramer said that GSIC is beating Amazon.com, Inc. (NASDAQ:AMZN), and he took another stab at AMZN as a violator of rules because it trades at more than two times its growth. GSIC trades really cheap to to its growth numbers, and, according to Cramer, is criminally undervalued.

Even though he said don't buy in after hours, the stock still traded up 7% to $18.80, although the 52-week range is $10.67 to $19.
