How to compare a deal: price per serve
A big discount on a small tub can still cost more than a small discount on a large one. Use this simple check:
- Take the sale price.
- Divide it by the number of serves on the label.
- Compare that number across the tubs you are looking at, and check the grams of protein per serve as well.
Larger tubs usually win on price per serve. Only buy a size you will finish before the best before date.
Tips for buying protein in a sale
- Pick your flavour early. Popular flavours sell out first.
- Not sure about a flavour? Ask in store. Many Supps247 stores let you taste before you buy.
- Pair it up. Stack and Save bundles combine protein with creatine or pre-workout for less than buying them separately, such as the Legit Muscle Stack.
- Hit free shipping. Orders of $99.99 or more ship free Australia-wide.

Common questions
Is Black Friday a good time to buy protein powder?
Yes, if you use it regularly. Protein keeps well, so a larger tub bought on sale usually gives a lower price per serve.
What is the difference between whey blend and WPI?
Whey isolate (WPI) is filtered further, so it has more protein and less carbohydrate, fat and lactose per serve. A blend usually costs less per serve.
Checked on 13 November 2026. Protein powder is a food supplement and does not replace a balanced diet. Check the label for allergens such as milk and soy. Always read the label and use as directed.
