Frito-Lay's contests, including the annual "Do Us A Flavor" promotion, are usually advertised on the Frito-Lay website as well as on external websites solely for those contests. You can view contest information on the Frito-Lay home page section titled "Always Something Good Going On" or on the "Snack Chat" blog.
Frito-Lay often posts contest information, including entry methods and eligibility rules, on external websites for each contest, such as DoUsAFlavor.com and Summer.Lays.com. In addition, Frito-Lay's parent company, PepsiCo, maintains an FAQ that includes links to contest rules and official websites. On the PepsiCo FAQ, several alternate entry methods are listed, including text messaging and entry through a participating retailer's website.
Frito-Lay also posts contest information on its social media accounts linked from the Frito-Lay website. Frito-Lay's Facebook and Twitter accounts usually have the latest information on contests and promotions, and they sometimes include direct links to entry forms.
Finally, Frito-Lay advertises its contests and promotions directly on its snack packaging. The bags with promotional information feature the contest website, along with some brief information on entries, odds and prizes. Additionally, packaging might contain a code to enter on a website, as is the case with the "Lay's Summer Days" contest.
