Things in bulk
"Sometimes when we buy in bulk, we wind up throwing the 'bulk' of what we bought in the trash; no one needs 10 pounds of honey mustard," says Rachel Cruze, a financial expert and author of Love Your Life, Not Theirs. "But there are times when buying in bulk is the best way to save." According to Cruze, one of those times is when you buy household goods at warehouse stores like Costco, which are generally cheapest across the board. "Stock up on things like paper towels, toilet paper, trash bags, and cleaning products to save money in the long run."

Gift wrap
For the holidays or birthdays, you don't need to spend much on gift wrap. Stock up on wrapping paper, gift bags, tissue paper, tape, and all of your gift-wrapping needs at a local dollar store. "While Walmart does have some good deals on these items, dollar stores are still cheaper," shares Cruze. "And don't forget to save all of the gift bags and bows you receive during the holidays to save money next year!" Find out 10 more things you should have been buying from the dollar store all along.

Diapers, wipes, and other baby supplies
When it comes to babies, especially newborns, it's true what they say: Babies are expensive. "I use Amazon's 'Subscribe and Save' option when it comes to baby goods that I know I need to continuously restock, like diapers and wipes," Cruze says. It saves you a couple of dollars each time, which makes a difference because those little guys go through them so fast. "Plus, the convenience factor of having them delivered to your door before you need them is priceless!" These are the strangest things you can buy at Walmart.

Batteries
"Around the holidays, parents are stocking up on batteries for the presents Santa will be leaving under the tree, so it follows that Walmart and supermarkets tend to have a high markup on them," says Cruze. "You're better off buying batteries in bulk at warehouse stores like Costco." These are the Kirkland products you should always buy at Costco.

Furniture
Just because a piece of furniture—from a bed frame to an end table—is inexpensive, that doesn't mean it's necessarily a great deal. "If you're redecorating, do your research before you snag the cheapest piece of furniture you can find," says Cruze. While the price tag for furniture might be cheapest at Walmart, you should think about the quality and how long it will last. "If it's not going to hold up for at least a few years, you might wind up spending more money in the long-run." Instead, advises Cruze, try searching for items through an online retailer like Overstock.com, since they typically don't have the overhead costs that brick-and-mortar stores have. "Or," she says, "you could consider saving a little while longer to purchase something that will last." Polite people will never do these things at Walmart.

Tires
If you are in the market for new tires, try Sam's Club or Costco, says Sara Skirboll, RetailMeNot's shopping and trends expert. "They will be a little cheaper than Walmart," she says. "Plus, Costco offers their members free tire balancing and rotations." Check out these 15 things you're not buying at Costco, but should.

Organic produce
If you're looking to purchase organic fruit and vegetables, according to a recent article in Kiplinger, Trader Joe's and Aldi usually have lower prices than Walmart. "Amazon Prime members should also check Whole Foods, as membership qualifies you for exclusive discounts on select items," adds shopping expert Trae Bodge. Also, says Bodge, if you shop at Whole Foods with your Amazon Prime Rewards Visa card, you'll receive 5 percent cash back on your purchases.

Books
It's hard to compete with Amazon when it comes to paperbacks. "For example, You Are a Bad*ss is on sale for $9.60 at Amazon and $14.60 on Walmart," Skirball noted at press time. Additionally, if you're looking for hardcover books, "they are typically around the same price on both sites." Here are 24 more things you should always buy on Amazon.

Electronics
While Walmart is very competitive when it comes to pricing of electronics, they don't always have the lowest prices, says Bodge. Prior to investing in a 4K TV or a Google Home device, take a look at the same item at competitors, like Amazon, Best Buy, Target, or Newegg. "You just might find a lower price elsewhere," she says.

Gift cards
According to Bodge, at Walmart stores and at Walmart.com, you can find a broad selection of gift cards, from brands like Dunkin' Donuts, AT&T, Starbucks, and Nordstrom. While this is certainly convenient, you'll be paying full price for these gift cards. Instead, use an online aggregator (which collects information from a number of sites) like GiftCardGranny.com, which has thousands of gift cards at a discount. Next, don't miss the 15 things you're not buying from Walmart—but should.
