Retailer BJ’s Wholesale Club Inc. is up for sale, according to a media report.

The asking price for Westborough, Massachusetts-based BJ’s could be $4 to 4.5 billion, according to a story in the New York Post.

Two private equity firms, CVC Capital Partners and Leonard Green & Partners, own BJ’s. The firms took BJ’s private in 2011 for $2.8 billion.  

BJ’s also was for sale this spring but took itself off the market after Amazon, thought to be a potential buyer of the retailer, announced in June it was buying Whole Foods Market, according to the story.

In 2011, Walmart Stores Inc. showed interest in buying BJ’s, according to the story.

BJ’s operates about 215 stores on the East Coast and in Ohio.
