In the past, Walmart has taken some steps to fight competition from dollar stores like Family Dollar, Dollar General and Dollar Tree.
But the retailer just took things a step further at its ongoing investor meeting.
Walmart is planning on building more than 240 stores under 50,000 square feet by 2013, Shelly Banjo at the Wall Street Journal tweeted. She's at the meeting.

The chains have also stepped up their food and cosmetics offerings lately.
