What counts as a good price for protein powder?

Compare on dollars per 20 grams of protein, not the sticker price on the tub — it is the only number that makes a big bag and a small one comparable. Bulk whey concentrate is usually the value floor; isolates, hydrolysates, and premium plant blends cost more per gram, sometimes for a reason you need and sometimes not. Subscribe-and-save discounts of 5–15% can flip which product wins, so factor the honest subscribe price in. Every review here does this division for you, and the cost-savings tables rank products straight on it.
