In the United States, the price of products in the basic basket makes a difference when it comes to choosing where to shop. Consumers look for chains that offer quality without giving up savings, especially on items that are consumed every day. That's where wholesale clubs like Sam's Club and Costco have found their ground.
Bulk buying has become the best strategy for families who want to fill the pantry without blowing the budget. Store brands like Member's Mark or Kirkland have shown that they have nothing to envy from gourmet brands like Kerrygold. The battle between retail giants is fought on the field of unit prices.

Sam’s Club’s advantage over its rivals
Sam's Club has managed to stay one step ahead in the breakfast category. Its cereal and oatmeal offerings not only convince with variety, but also with prices that clearly beat those at Target, Walmart, or Kroger. For many shoppers, this difference is what determines loyalty to the chain.
A clear example is the popular Honey Nut Cheerios cereal. While at Costco a 1.3 qt. (1.2 liters) package costs more than $8, at Sam's Club the same product can be found for $7.60. At Walmart, however, that same box can reach $12.50, almost double the wholesale price.

The situation repeats itself with Quaker Old-Fashioned oats. Although Kroger and Costco keep prices close, Walmart is once again exposed. Shopping at Sam's Club means obvious savings that add up with every visit.
The secret: compare by unit price
Beyond the absolute numbers, what really determines savings is the unit price. Only then is it possible to measure which chain offers the best value for each gram of product. Sam's Club has become a benchmark because its unit prices win in most comparisons.
It's not just about bringing large quantities home, but about taking advantage of the quality and price stability that this format offers. Even if a consumer doesn't need that much cereal or oats, it's worth stocking up because of the accumulated difference. The key is simple: more for less.
Anyone who visits a Sam's Club warehouse will also find other grocery categories with prices that beat Costco and the rest of the chains. But in the case of cereals and oats, the savings are so obvious that they've become the symbol of the KO to the rest of the competitors.
