Four checks before you buy
1. Compare price per serving, not % off
A big “40% off” on a small tub can still cost more per scoop than a regular price on the large size. Divide the price by the servings on the label.
2. Check who sells it
Prefer “Ships from and sold by Amazon” or the brand’s own storefront — unknown third-party sellers are where expired or fake tubs turn up.
3. Look at the expiry date
Clearance stock can be close to its best-by date. Fine for something you’ll finish soon, not for a 5 lb tub.
4. Stock up on what you already use
The best Black Friday buy is the creatine, protein or magnesium you take anyway — not a new product because it’s on sale.
