NEW YORK (TheStreet) -- New Walmart CEO Doug McMillon is hitting the ground running.

Since taking over in February, McMillon has mostly been taking flak for dirty stores, low staffing levels and complaints from low-paid workers.

But now McMillon is ready to play some offense. The Walmart he is building plans to be a different company, more ubiquitous, and a better bargain.

First, and perhaps most important, is that Walmart is no longer willing to be only that darkness on the edge of town. The company, which developed as the one choice for bargains in small towns, and expanded into an all-in-one retailer whose Supercenters replaced small town centers, is now moving in many different directions, all at once.

Walmart now has six different store formats it can place anywhere, including convenience store-gas stations that compete with Chevron and Exxon-Mobil , Sam's Club warehouses to compete with Costco , Neighborhood Market stores that compete with Kroger , Walmart Express stores that compete with Family Dollar , alongside the traditional Walmart Supercenters and its original discount stores.

This brings Walmart into every major niche in retailing, including areas without a single national competitor. The convenience store market, for instance, is highly dispersed, with 7-Eleven being just the largest among hundreds of players, and formats ranging from just a few pumps to the giant Buc-ees in Texas, which can be more than 60,000 square feet.

Online efforts represent a seventh channel, or they could represent an eighth as the company looks to add pick-up windows for online shoppers to some of its existing outlets, in an effort to compete with Amazon.com .

Walmart has often run price comparison ads in various markets. Now it's taking that online through an app it calls the Savings Catcher, collecting customer receipt numbers and comparing what was paid with what other stores in the area charged for the same goods.

The company's mobile apps also list specials, show where they are when you're in the store, check product availability and handle customer shopping lists.

Walmart is also aiming to get high-income customers back into its Supercenters with irresistible bargains.
