Some things work in mysterious ways, but grocery store promotions are pretty straightforward in their scheduling tactics. Everyone knows most people are paid at the beginning or end of each month, and grocery marketing teams smartly push particular deals at these times. It's called the paycheck cycle and it assumes that people have more disposable income to spend at the start of the month than they do toward the end — otherwise known as living paycheck to paycheck.
More expensive items are promoted around the first while stores push cheaper products toward the thirtieth keeps items moving off shelves and boosts store sales. As a consumer, it's important to look beyond promotions to determine what items offer true value, no matter what time of the month. One thing is for sure: the announcement from Frito-Lay in North America that 20 percent more product will be added to bags of its corn-based Tostitos, Fritos, Cheetos and Doritos, at no extra price, is good news for snackers who have been frustrated by bags full of mostly air. It's all about getting more for your money these days.
