The strongest thread takeaway is protein powder, especially Optimum Nutrition versus Kirkland Signature. ON gets praise for better taste, easy mixing, and strong value at 80 servings for $50, while Kirkland is described as decent but less flavorful and not as smooth. Flavor preferences lean toward chocolate and vanilla, with some favoring Ascent or Levels for cleaner ingredients and less artificial sweetness. A few caveats surface around water mixing, sweeteners, and lead concerns in protein powders, so the sale looks most appealing if taste and ingredient profile matter most.

  • Optimum Nutrition protein powder can taste better and mix more easily than Kirkland Signature during the savings period.

  • Costco's Optimum Nutrition deal can offer a strong per-serving price for stocking up across the year.

  • Costco's return and refund options can help reduce risk if a protein powder flavor does not work out.

  • Costco's price adjustment process can be handled through a self-service portal with responses taking a few days.

  • Protein powders can raise safety concerns because investigations have found concerning lead levels in many popular products.

  • Optimum Nutrition may not taste as good when mixed with other flavors, even if it tastes better by itself.

  • Kirkland Signature protein powder can taste worse and may mix less well for some buyers.

  • The promotion thread can be confusing because it is labeled a coupon book even though no coupons appear to be included.

How do you like that mattress?
I like it a lot. It's firm but plush on the top. Perfect balance. Best budget mattress I've tried so far.

I wish they would stop with the "$5 off" or such. Just tell me the total price. $ off doesn't mean squat
I'm guessing they do this to allow for price variation by location?

Can you do investments with this for free? Or is it like one of those "free" returns where it's only for 1040EZ and no state.
free Federal, $15 state (I think), handles all tax situations I've come across, very user friendly, highly recommend

Which one is better between Optimum Nutrition protein powder and Kirkland Signature protein powder?

They will both be the same price for the same weight during this promotion period.
One more thumbs up for Ascent, purely based on the ingredient list.

Yeah, nothing special. Not sure why it gets front paged every time. Thumbs up for the effort though.

Strange! For me, on imgur I just scroll down, and no ads. Maybe my Ghostery ad blocker takes the ads out. It's free too.
For every one of these Costco coupon book threads, they put up a link to the scanned pages on imgur, so I took the time to scan each page to do that for your benefit.

Could it possibly be worse than CostcoInsider? EEK!

Dude you can get 53 and 1/3 glizzies with that $80 and finally become the ultimate glizzy gobbler.

ON is 80 servings, Kirkland is 70. If everything else is equal, the ON sale is pretty good. I'm a fan of the ON Extreme Milk Chocolate for sure!
