Check out These Money-Saving Alternatives to Costco and Sam's Club

When people think about bulk shopping, Costco, Sam's Club, and BJ's usually come to mind. They are, after all, the leaders of the pack.

But what if we told you that warehouse clubs aren't the only retailers that reward bulk buying? And, more importantly, would you be willing to stray from your favorite club if it meant saving a few extra bucks?

When it comes to products like toilet paper, non-perishable food items, and cleaning supplies, it's no secret that buying in bulk can save you money. As consumer savings expert Andrea Woroch recently explained to CNBC, this is mainly because "buying larger quantities typically means a better price per unit." But, it's possible for bulk shoppers to save even more money simply by looking outside the box (pun intended) and hitting the internet—no membership required.

While WebstaurantStore.com is geared toward supplying restaurants, it also sells plenty of products ordinary people use in their homes. As CNBC points out, you can find cleaning supplies, paper towels, and cooking oils, all in bulk, and often for a deal.

CleanItSupply.com offers a similar wholesale service for janitorial, restaurant, and office supplies. Here you can find bulk deals on everything from dish soap to trash bags. But keep in mind that going this route might require a little extra effort. For example, buying large amounts of household cleansers in concentrated form requires you to dilute them yourself.

No matter where you get your bulk shopping fix, just remember to check the price per unit and price compare to make sure you're actually getting a good deal.
