Don’t Buy: Kirkland Laundry Detergent

Kirkland is a well-recognized brand in stores like Costco and Sam’s Club, and its brand has gained a host of loyal followers since its rollout. Kirkland detergent does the job well, but its effectiveness fades over time.

Buying detergent in bulk makes sense if you have young children or a large and messy family. Since most detergents have a shelf life of four to six months, you may want to consider a smaller container for maximum potency.
