Despite the obvious discounts that come from buying items in bulk, doing so is not always a smart move. That’s because purchasing too much, even of a good thing, can lead to waste and clutter. There are some cases, though, where buying a lot of something at once can actually be a good move for your wallet. Here are 10 items to buy in large quantities:

1. Toilet paper

Buying this essential paper product in bulk can be up to 50 percent cheaper than buying a few rolls at a time. So find a place to store some extra toilet paper (try under your bed if you run out of cupboard space in the bathroom) and save yourself a few bucks. Just make sure you always store it in the same place, so you know where it is and don’t buy even more when you’re already fully stocked.

2. Soap and shampoo

Buying these items in bulk saves a few cents an ounce on shampoo or per bar of soap. While this may not seem like very much, it adds up over time. Since you know from your washing habits how often you need to replenish your supplies – perhaps you go through one bottle per month – you can easily buy a few containers at once in advance to score the discount.

3. Office supplies

The next time you need office supplies such as pens, folders or staples, be sure to buy them in bulk. Doing so can save you up to 50 percent off the price you would have paid if you didn’t buy in bulk. Whether you compare prices online at big office supply stores or prefer to visit the grocery store or discount store in person and stroll through the aisles, you can usually get a better deal by stocking up on items you know you’ll need – and use.

4. Toothbrushes and toothpaste

If you practice good dental hygiene, and we hope you do, then you purchase new toothbrushes and toothpaste every few months (or at least you should). You could either buy two toothbrushes for $8 or six for $14. Similarly, you could buy a tube of toothpaste for $5 or get three for $10. If you’re buying for your whole family, then the available savings are even bigger.

5. Vitamins

Spending money in the name of health is always a good idea; be sure to read up on the latest recommendations to pick the vitamins that provide the biggest benefit. You can save a few cents per pill by buying in bulk. Again, this may not seem like much, but over time, the savings add up.

6. Pantry items

When it comes to buying food items that will not perish quickly, such as cereal, canned tuna or soft drinks, opt to buy in bulk. Doing so is typically 30 percent cheaper than just buying one box, can or drink at a time. Just be sure to stick with items that have a long shelf life to reduce the chance the items go to waste. Paper towels, cotton swabs and cereal are all among the most popular items purchased through Amazon Prime Pantry, which can offer lower prices than brick-and-mortar stores when multiple items are purchased at once.

7. Coffee

Whether you grind your own beans or use K-cups, purchasing coffee in bulk can significantly reduce the costs of your caffeine habit. Signing up for automatic delivery through a monthly delivery service also ensures you’re never out of your morning pick-me-up.

8. Diapers

If you have babies in the house, then you’re probably constantly buying diapers. Save yourself some cash by using Amazon Subscribe & Save or a similar service to keep yourself well-stocked while benefiting from discounts.

9. Batteries

You don’t want to notice you’re all out of batteries when the lights go out and you can’t find a working flashlight. Stock up on batteries by buying large packages of them to get the best deal and also make sure you don’t run out at key moments.

10. Detergent
