1 thought on “Kirkland Protein Bars Review – Best Costco Protein Bar?”

  1. Costco chocolate chip and fudge protein bars are a staple for me. You are being kind when you say the oreo bar tastes a lot worst. That flavor should not be sold and certainly not be sold with the peanut butter bars. The packaging arrangement for the peanut butter bars and oreo bars make the peanut butter bars twice as expensive as the chip bars and oreo bars. I just throw away the oreo bars if I buy the peanut bars.
