Lay's
Lay's is the largest brand, by a sizable margin, in the United States. Originally called the H.W. Lay company, the company merged with Fritos in the mid-twentieth century.
Perhaps every major national retail food chain, gas station or sundry store carries Lay's chips.
The brand offers several static flavors, as well as occasional "limited edition" brands. The current flavor roster includes the following (excluding Stax and Air Pops):
Barbecue Cheddar & Sour Cream Cheesy Garlic Bread Chile Limon Classic Deli Style Original Dill Pickle Flamin' Hot Garden Tomato & Basil Honey Barbecue Lightly Salted Limon Pico de Gallo Salt & Vinegar Simply Sea Salted (thick cut) Sour Cream & Onion Sweet Southern Heat Barbecue Tapatio Limon Applewood Smoked BBQ (Kettle) Jalapeno Cheddar (Kettle) Original (Kettle, Wavy) Lattice Cut Aged Cheddar & Black Pepper (Kettle) Lattice Cut Roasted Garlic & Sea Salt (Kettle) Maui Onion (Kettle) Mesquite BBQ (Kettle) Sea Salt & Cracked Pepper (Kettle) Sea Salt & Vinegar (Kettle) Au Gratin (Wavy) Hickory Barbecue (Wavy) Lightly Salted (Wavy) Ranch (Wavy) Roasted Garlic & Sea Salt (Wavy)
