21 Best Bulk Buys from Costco that Will Last You All Year (and Save You Money)

Costco is a great place to go for bulk buys. You can really get a great deal and save money in the long run. Plus, it’s convenient because you buy it once and it lasts all year. The only downside with buying in bulk is that many of these products last a really long time, a year or longer, so they take up precious pantry or fridge space. But despite that, the savings and convenience make it all worthwhile. Here are the best Costco bulk buys that last me a year (or longer).

Plastic Wrap

This is the one Costco bulk buy that makes me laugh — it lasts forever! The Kirkland Plastic Food Wrap comes in a giant two-pack roll. Since I’m not a heavy plastic wrap user, it lasts me several years!

Vitamins

Costco consistently has the lowest prices on vitamins, making it my go-to place for bulk buying. The best part? These vitamins last for ages! For example, a bottle of Kirkland Vitamin D contains 600 capsules — that’s almost two years’ worth if you take one a day. Similarly, Kirkland Vitamin C comes with 500 capsules, ensuring you’re stocked for a long time.

Batteries

Batteries are another must-buy at Costco. Their prices are unbeatable, and a pack of 40 AA or AAA batteries usually lasts me a year or two.

Cough Syrup & Cough Drops

I always stock up on cough syrup and cough drops from Costco because buying in bulk saves me money. It’s helpful to have them on hand in case someone in the family gets sick. A pack of 200 cough drops and the cough syrup pack usually lasts us the entire year unless we experience an unusually high number of colds.

Paper Plates

I buy paper plates in bulk at Costco because it’s a great deal. My go-to plates are the Chinet classic white plates because they are sturdy and won’t collapse, even with saucy food. A pack of 225 plates lasts my family a year unless we have a large party.

Maple Syrup
