Late Monday, The Wall Street Journal reported that Walgreens approached Amerisource about buying the three-quarters of the firm it doesn’t already own. Amerisource shares skyrocketed more than 25 percent after-hours Monday, and were up more than 8 percent late morning Tuesday.

Despite being a possibly risky move for Walgreens, Cramer said it’s a great time for Amerisource to sell itself.

“I would sell” because Amazon “wants to cut out the middleman,” said Cramer, host of “Mad Money.”

Amazon has made other attempts to enter the health-care industry. CNBC has previously reported the e-commerce giant was in talks with generic drugmakers about a potential entry into the pharmacy space.

The Journal reported Tuesday that Amazon is gearing up to launch a larger offering in the medical supplies business, sending shares of health-care supplier and services companies McKesson, Cardinal Health and Owens & Minor lower.

None of the companies mentioned were immediately available to respond to CNBC’s request for comment.
