13 Sam’s and Costco Bulk Buys That Actually Save Money in 2025
If you choose carefully, buying in bulk can be a smart move. Some products consistently save money without sacrificing quality or freshness, but not all warehouse deals actually reduce costs. Knowing what to buy in bulk in 2025 can significantly impact your budget, whether you’re stockpiling for convenience or feeding a large family. These 13 Costco and Sam’s Club bulk purchases are well worth the money this year.
1. Toilet Paper
Sam’s and Costco continue to provide great deals on household necessities like toilet paper. When compared to supermarket brands, bulk packs can save up to 25% on per-roll costs, making them one of the best investments even in 2025 when prices remain steady. Because of its nearly infinite shelf life, it’s a stress-free way to stock up for months at a time.
2. Paper Towels
Paper towels are still a dependable bulk purchase, particularly for homes that use them frequently. High-quality multi-roll packs are available at both warehouse stores for significantly less per sheet than smaller packages. They are long-lasting, easy to store, and capable of handling anything from effectively drying produce to cleaning up spills.
3. Laundry Detergent
Bulk laundry detergent purchases result in significant cost savings per load. At about half the price, Sam’s Club’s Member’s Mark and Costco’s Kirkland Signature brands outperform top national brands. Concentrated formulas reduce waste and plastic bottle usage, which is in line with the sustainability targets for 2025.
4. Batteries
One of those things that always seems to run out at inconvenient times is batteries. Bulk packs of AA and AAA batteries from warehouse clubs have long shelf lives and cost between 30 and 40 percent less per unit. They are a useful, long-lasting investment because they work well for remote controls, children’s toys, and emergency flashlights.
5. Coffee
If you drink coffee every day, buying whole beans or ground coffee in bulk can save you a lot of money. Premium options like Starbucks and Lavazza are available at reduced prices at Sam’s and Costco. Caffeine lovers can enjoy consistent quality without having to make frequent trips to the grocery store because they keep their flavor for months when stored in airtight containers.
6. Olive Oil
In bulk, extra virgin olive oil is frequently less expensive at warehouse clubs, where big containers provide quality comparable to gourmet shops at a significantly lower cost. It’s a great pantry purchase in 2025 due to stable import prices. Simply use a smaller decanter for everyday cooking and keep it in a cool, dark location.
7. Canned Beans
Protein-dense, durable, and among the most economical bulk staples are canned beans. The cost per can can be reduced by up to 40% when purchasing multi-can packs at Sam’s or Costco. When stored properly, they stay fresh for years and can be used in a variety of soups, salads, and stews.
8. Frozen Fruits
A cost-effective and healthful option is frozen fruit. Both stores sell premium berries, mangoes, and mixed fruits in bulk bags that are ideal for baking or smoothies. They preserve nutrients and minimize waste by enabling portioned use over time because they are flash-frozen at their ripest.
9. Cheese
If stored properly, bulk blocks or shredded cheese can be a good deal. Dairy prices are stable in 2025, so bulk cheese options from Costco and Sam’s are less expensive per pound than those from supermarkets. To preserve freshness without spoiling, divide into smaller portions and freeze.
10. Pet Food
Buying pet food in bulk or in multiple packs can result in significant cost savings for pet owners. On average, warehouse clubs’ bulk prices are 20–35 percent cheaper than those of pet stores. To guarantee a long shelf life for the food your furry friends eat, look for sealed packaging and verify the expiration dates.
11. Trash Bags
Another bulk essential that hardly ever goes bad is trash bags. Sam’s and Costco frequently offer bags for 30% less than their grocery store counterparts. You can avoid frequent shopping trips and make sure you never run out of this household essential by using large boxes that last for months.
12. Nuts
Nuts such as cashews, pistachios, and almonds are costly when purchased in small quantities but reasonably priced when purchased in large quantities. Costco and Sam’s sell them raw or roasted in big, resealable bags that preserve freshness. They make great, healthful snacks for the whole family and are high in protein and shelf-stable.
13. Over-the-Counter Medications
Vitamins, painkillers, and allergy medications are much less expensive in warehouse-sized bottles. Although they are 50% less expensive, generic brands frequently have the same active ingredients as name brands. In 2025, this category regularly offers significant savings due to its lengthy expiration dates and frequent promotions.
