Are Supplement Sales Real? We Checked 1,688 Crossed-Out Prices

Five weeks before Black Friday, we checked every crossed-out supplement price in the US and UK stores we track against what the product actually sold for in the month before. Few were real discounts.

Frequently asked questions

What is the difference between "Real price drops" and "Store sales"?

"Real price drops" are based on the price history we collect: a product is listed when its current price is below the highest price we saw for at least a week in the last 30 days. "Store sales" show the old and new prices a store displays on its own site, which we have not verified yet.

How often are prices updated?

The stores we track are checked automatically four times a day, and prices update as they change.

Do I buy the product from WheyProof?

No. WheyProof is a price tracker, not a store. "Go to store" takes you straight to the brand's or retailer's own site, and the purchase happens there.

Where do the coupon codes come from?

Coupon codes are not collected automatically. To avoid showing expired or wrong codes, we only publish codes we have checked by hand.

Why do some products show no price per serving?

We only show it when the brand publishes the serving size and the package weight; we never show an estimated number.
