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.

I think quality/macro wise they're pretty comparable. Go with whatever tastes better to you.

Aww yiss, the Ajinomoto gyoza are top shelf, for frozen dumplings. I keep worrying that they're going to roll them off. Guess I should stock up.

I've been hovering the Plus Prosser mattress (King/Firm) for like 2 months, it's actually on sale now. ($1k down to $800)
Seeing that image of the novafoam reminded me to look, so thanks for that.

Also, my current novafoam has a huge dip in the middle, so buying this to replace it - really crap mattress for $800.
But I'll return to Costco and get an even swap! Infinite free mattresses hack.

Imgur is definitely better than the hemorrhoid that is CostcoInsider, but damn, Imgur went to heck too. Panning and zooming is basically unusable.

I have always had Kirkland Signature Whey protein powder. It's quite good without any issues. Taste, texture, and everything is good. Is Optimum better because it's normally higher priced, but will be the same price as KS during the savings period?
