In the increasingly crowded world of daily deal sites, Aisle50.com is scheduled to launch on Monday morning.

Instead of offering up teeth whitening sessions or horseback riding lessons, Aisle50 will be selling groceries at an average discount of 50 percent off retail price.

“It’s stuff everybody uses at a store you already shop at,” said Christopher Steiner, 34, one of the three founders of the Silicon Valley startup, believed to be the first daily deal site in the country exclusively selling groceries.

Aisle50, which eventually plans to go nationwide, is launching in North Carolina and South Carolina in a partnership with Winston Salem-based Lowes Foods.
