Lay's, the nation's largest salty snack maker, announced on Friday plans to roll out Lay's Wavy Potato Chips Dipped in Milk Chocolate, next week. 

The chocolate-covered potato chips, which will sell for $3.49 per 5-ounce bag, are being shipped to Target stores only and will be available for a limited time, through the holidays. 

According to USA Today, the chocolate-covered chip also ties in with a flood of seasonal, limited-time-only snacks that increasingly hit the market between Halloween and New Year's. The rollouts will only be sold at Target stores. 

"When you try something drastically different, you have to walk before you can run," Ram Krishnan, vice president of marketing at Frito-Lay, the parent company of Lay's, said. "We wanted to test our way through this before we go big."

Krishnan said if the chocolate potato chip is a major hit, it could become permanent and also expand into other combination flavors including dark chocolate, white chocolate and even peppermint.

Snack foods are a $31 billion market and growing, reports IBISWorld, the market research specialist. About 43 percent of consumers now snack three to four times daily, compared to 24 percent in 2009, according to Symphony IRI, the research specialist.

"Flavors are getting more sophisticated and complex," Tom Vierhile, innovation insights director at DataMonitor, the consumer products research firm, said. "We are seeing more products that may pair traditional flavor opposites like sweet and salty." 

According to USA Today, over the past year, sweet and salty snacks include, Kettle Maple Bacon Potato Chips, Planter's Sweet & Salty Snack Mix, ConAgra's Crunch 'n Munch and even Sweet 'n Salty Bugles.
