While you might not consider nuts to be a food that spoils particularly quickly, those with a high fat content actually can go rancid after just a few months, which is why we think they're one of the foods you should never buy at Costco. Macadamia nuts, Brazil nuts, and pine nuts, specifically, have shorter lifespans than most due to their high fat content, and walnuts and pecans are known for spoiling faster than other varieties for the same reason.

Die-hard Aldi shoppers have their grocery shopping experience down to a science. They come equipped with a handy-dandy quarter for the shopping cart, bring their reusable bags, and know exactly how to organize their grocery list in the same order as their store's aisles for max efficiency, including a stop in that beloved "Aisle of Shame." With the knowledge of all their favorite Aldi-brand products and weekly Aldi Finds, these shoppers also know which items are a must-grab and which are a hard pass.

Even foods people love end up on the frequent return list at Costco, and there are plenty of reasons why. Knowing which ones end up being returned and why can help you keep an eye out for potential problems and give you insight into some interesting customer buying habits. Unsurprisingly, many of the items that people frequently return to Costco are fresh ones that spoil easily.
