Buy: Kirkland Vitamin Water
You might not know it, but the fruit-flavored, no-calorie and mineral-rich Kirkland Signature Vita Rain Zero are incredibly similar to Glaceau Vitaminwater Zero. Both are sold at Costco, mind you, but there is practically no taste difference. Of course, there is a significant price difference. Kirkland’s 24-count variety pack of 20-ounce Vita Rain Zero costs $9.99. A case of Glaceau Vitaminwater Zero cost $15.99.
Don’t Buy- Kirkland Laundry Detergent
Kirkland laundry detergent is a good way to save some money, but that’s about its only pro. You’ll end up using the money you saved buying new clothes since your low-quality detergent ruined your others. Not only is it bad for your favorite jeans, but it’s also caused allergies and reactions in addition to respiratory problems and asthma. If that’s not enough to deter you, it’s also terrible for the environment.
