Amazon is set to report earnings on Jan. 29, and Fast Money's Guy Adami says to buy the stock now.

Back in October, Amazon got crushed, hitting its 52-week low after a disappointing earnings report. Adami thinks the best way to play the stock is to buy it now and then to find another chance to buy the stock on the dip. "Look for a subsequent pullback back down to $280, I think you'll be able to round turn this thing," explained Adami.
