Research notes
Zero Carb isn't sold in chocolate (Isopure's Dutch Chocolate is in the Low Carb line), so this uses Creamy Vanilla, the Zero Carb flagship. The Amazon listing is titled '3 LB', but its product image shows a 2.73 lb (1.24 kg) tub with about 40 servings, which matches the brand's label ('About 40 servings per container'). Price is Amazon's current one-time price (sold by Amazon.com, no deal badge). Amazon's strikethrough List Price of $89.99 is not used. The brand's own store listed the 40-serving (2.73 lb) tub at $103.49.
