First it was available in c-stores only. Now it’s available in the grocery freezer case. Doritos Loaded was so popular at 7-Eleven stores, Frito-Lay decided to debut a boxed version that consumers can enjoy at home. "Doritos celebrates people stepping outside of their normal routine and doing new things," said Marissa Solis, vice president of marketing, Frito-Lay North America. "That definitely applies to Doritos Loaded, a snacking experience that takes bold to the next level.”
