It’s no secret that when you shop in bulk at Costco, you are likely to save yourself some money. How much? Well, if you are being smart, you could save thousands of dollars over time just by making the right choice of what to stock up on from your favorite wholesale retailer.
The following items are classic Costco purchases you should already be making, but if you aren’t, there is no time like the present. Even if you don’t have a huge household or aren’t sure if it’s worth spending the money upfront, you’ll be sure to see the savings when you add up your receipts.
Here are four big buys from Costco that can add up to a savings of thousands of dollars:
1. Batteries
There are always appliances and electronics to power, not to mention emergencies where you might not be able to use your normal source of electricity. Buying a 48-pack of Kirkland Signature Alkaline AA Batteries only costs $16.99, roughly breaking down to 35 cents per battery. Cheaper than most name brand batteries, Costco makes sure you are never without power.

2. Trash Bags
Let’s face it: There’s always going to be trash, and you will always need to find a place to put it. Why not stock up on Kirkland Signature 13-gallon kitchen trash bags from Costco, where a 200-count box tends to go for $19.99.
Not convinced? Countless Reddit threads frequently list trash bags as a top item to stock up on in order to save money. When you purchase them at Costco, those big buys end up as big buck savings.
3. Toilet Paper
We all use it, and it never spoils or goes out of style. Toilet paper might be the one product that connects the entire human race, and when you buy the Kirkland Signature brand 36-roll bulk pack of bath tissue, you’ll only be spending roughly $24.96 — but saving much more.
The cost per roll is drastically lower versus going to your local grocery store for a much smaller package. Also, you never want to be caught without a back up supply.
4. Paper Towels
In the same vein of savings when it comes to toilet paper, paper towels are a product that you can buy in bulk, store at home and use as needed for as long as it takes for you to run out.
From spills in the kitchen to messes in the bathroom, you can pick up Kirkland Signature 12-packs — also available in 2-ply — for $23.99 to save thousands of dollars in the long run that would have otherwise been spent at your local store in a less cost-effective way.
