Walmart isn't worried about the dollar stores but they are both riding the cheapskate trend.
The nation's dollar stores, those once-dowdy chains that lured shoppers by selling some or all of their merchandise for $1, are suddenly hot. They are busily opening new stores, outfitting existing stores with refrigerators and freezers, and sprucing up their aisles with better lighting, fresh paint and new signs.
And while most big retail chains are closing stores and radically cutting back on new outlets, the dollar chains are planning to open hundreds of stores this year in some of the best locations to which they have ever had access.
Dollar stores have long had a reputation for being down-at-the-heels places to buy cheap, generic goods. While keeping their low prices, they are revamping their image and climbing the respectability ladder - in some cases into the Fortune 500.
Dollar General, long part of that select club of the 500 biggest American companies, appears on this year's list at No. 259, up 15 places from last year. And Dollar Tree landed on the list for the first time, at No. 499.
