While buying a certain brand is a good idea sometimes, there are some items in particular that are always cheaper -- and just as effective -- in generic form. They are:
1) Over-the-counter medications.
2) Flour, sugar, salt, and spices.
3) Cleaning products.
If you're really worried about brand name vs. generic, read the ingredient labels! Chances are, they're identical and you can put your mind at ease knowing you're putting the exact same things in your home and body, but for way less money.
