Costco gets plenty of attention, but it isn’t always the best place to buy every bulk item. Many shoppers who compare prices closely find that Sam’s Club often has the better deal on certain everyday staples.
If your goal is to get the most for your grocery budget, the details matter. A lower price per unit, a package size that fits your household, and products you actually buy every week can make a bigger difference than a flashy display or limited-time item.
For families stocking the pantry, packing lunches, buying baby supplies, or keeping the freezer full, even small savings can add up over time. That’s why it pays to compare stores instead of assuming one warehouse club always comes out ahead.
These are the bulk items that are often worth buying at Sam’s Club instead of Costco.
Fresh Produce
Produce is tricky at any warehouse store because you’re buying larger quantities. Sam’s Club often carries slightly smaller bulk packs compared to Costco, which can reduce waste for smaller households.
Many shoppers also report better consistency in certain produce items, such as grapes and salad kits. Pricing is usually competitive, and for families that move through produce quickly, it’s often the better option.

Baby Products
Sam’s Club often carries a wider range of baby supplies, including multiple diaper brands, wipes, formula, and baby snacks.
More variety means you’re less likely to have to switch brands. Pricing is competitive, and for parents buying these essentials regularly, Sam’s frequently offers better overall value.
Household Staples
Paper towels, toilet paper, trash bags, cleaning products, and pantry basics are categories where Sam’s Club regularly competes hard on price.
In many cases, Member’s Mark products are slightly cheaper per unit than Kirkland equivalents. For items you buy every month without fail, that steady savings can make a noticeable difference over the course of a year.
Rotisserie Chicken
Both stores are famous for their five-dollar rotisserie chickens, but Sam’s Club frequently edges out Costco on price by a small margin. While the difference might be only a few cents, taste is where many shoppers say Sam’s wins.
Jasmine Rice and Bulk Grains
If rice is a pantry staple in your home, Sam’s Club is often the better place to stock up. Large bags of jasmine rice are typically several dollars cheaper than similar-sized bags of Kirkland rice.
Over time, that price difference matters, especially in households that cook rice weekly. The packaging is also clearly labeled, and the nutritional comparisons are comparable or slightly favorable.
Olive Oil and Avocado Oil
Cooking oils are one of those items where bulk buying makes sense, and this is where Sam’s often delivers better per-ounce pricing.
Member’s Mark olive oil frequently comes in larger bottles for only slightly more than Costco’s smaller size. The same goes for avocado oil, where Sam’s pricing tends to be marginally lower per fluid ounce. For households that cook daily, those savings are steady and reliable.
Breakfast Cereal and Variety Packs
If you have kids or just like convenience, cereal multi-packs are a regular purchase. Sam’s Club often beats Costco on price per ounce, especially for name-brand variety packs.
Costco sometimes offers slightly larger boxes, but when you calculate the price per serving, Sam’s frequently comes out cheaper, which is what really matters.
Bakery Cakes and Custom Desserts
Sam’s Club bakery consistently outperforms Costco in customization and convenience. Ordering cakes is easier, design options are broader, and pricing is competitive or cheaper.
Sam’s offers tiered cakes, themed designs, sports decorations, and custom cupcake options that Costco does not match in scale. For birthdays, graduations, or team celebrations, Sam’s gives you more flexibility.
Coffee Pods
Single-serve coffee pods are another category where pennies add up. Member’s Mark coffee pods usually cost a few cents less per pod compared to Kirkland’s.
Over a year, even small differences can add up to double-digit savings for daily coffee drinkers. Sam’s also tends to offer more seasonal flavors and variety packs.

Snack Chips and Lunch Packs
Bulk chip variety boxes are often noticeably cheaper per bag at Sam’s Club. Even when Costco includes a few extra bags in a case, the cost per individual serving is usually lower at Sam’s.
If you pack school lunches or stock up for gatherings, this is one category where Sam’s consistently wins on everyday value.
Nut Bars and Protein Snacks
Member’s Mark nut bars are typically slightly cheaper per bar than Kirkland’s equivalent. Nutritionally, they’re comparable, sometimes even slightly lower in calories or carbs.
Since these bars are a repeat purchase for many households, the small cost difference makes Sam’s the smarter choice over time
Deli Meat and Bacon
Sam’s tends to carry more recognizable national brands in its deli section. Thick-cut bacon options and bulk deli meats are frequently praised for both price and consistency.
For households that go through sandwiches and breakfast staples quickly, Sam’s offers strong value here.

Same-Day Delivery
If you use grocery delivery, Sam’s Club can be significantly cheaper. Same-day orders typically involve a flat fee instead of the larger markups that Costco adds through third-party services.
For large grocery orders, that difference can be substantial.
