It’s easy to be wooed by a fancy label and a well-known name, but when it comes to many products, the generic version is just as good (if not better). So, if you’re looking to cut a few bucks off your next grocery bill, start by swapping out these five products.

Go for store brand water

Guess what? An estimated one quarter or more of bottled water comes from the tap. Given those odds, you’d be just as well-off (or better, perhaps) buying a filter and drinking what you get for free. If you absolutely must buy bottled water, go for store brand–experts say there is no difference between that and the expensive stuff.

Save on sunscreen

Sunscreens are regulated by the FDA–that means no matter what brand you get (even if it’s generic), it’s held to the same standards. Look for a package with the phrase “broad spectrum SPF” followed by an SPF number on the front. Federal law says manufacturers can only use that phrase on products that have passed a broad-spectrum testing procedure.

Get medications on the cheap

Like sunscreen, medications are regulated by the FDA. That means that both generic and brand-name medications have to conform to the same standards, including safety, effectiveness, and quality. So why does brand name cost so much more? The original pharmaceutical company has to pay for research, development, and marketing approval–a process which could add up to billions of dollars.

Skip the name brand milk

Like many grocery products, generic milk will often come from the same manufacturer as the pricier store brands. Plus, if it comes from a local dairy, it’ll be much fresher. It’s worth noting, however, that the same rule doesn’t apply to all other dairy products: generic yogurt, in particular, often has noticeable texture differences.

Stock up on (cheap) pantry staples

Studies have found that professional chefs and food preparers buy store brand staples 77% of the time. Items such as salt, sugar, baking powder, condiments, and teas are typically the same, no matter whose name is on the front. The truth is, if you insist on buying brand name ketchup, you’re paying more than you need to.
