Optimum Nutrition Cashback
Links here are refer-a-friend links — Scrimpr may earn a small bonus, the same as if a friend referred you. It never changes your rate, and the ranking is purely by what each site pays you.
Optimum Nutrition cashback — ranked
Cashback isn't guaranteed on everything — gift cards, marketplace or third-party sellers, and orders using an outside voucher code are commonly excluded. Check the site's Optimum Nutrition terms before you buy.

How Optimum Nutrition cashback works
- Pick the top-paying site
Click through to Optimum Nutrition via its link in the table above.
- Shop as normal
Finish checkout in the same browser session — don't switch device or reopen later.
- Wait for it to track
Tracking shows in days; payable cashback often takes weeks once Optimum Nutrition confirms the order.
Make sure your Optimum Nutrition cashback tracks
Most "missing cashback" comes down to a handful of avoidable mistakes. Do these and your Optimum Nutrition purchase should track cleanly:
- Accept all cookies at Optimum Nutrition. Cashback is tracked with cookies — reject them and there's literally nothing for the site to record.
- Turn off ad-blockers and privacy tools. uBlock, Ghostery, Privacy Badger and Brave Shields all block the tracking pixel. Disable them for the purchase (or use a clean browser).
- Disable other shopping extensions. Honey, Pouch and rival cashback add-ons grab the "last click", so they quietly steal the referral. Turn them off before you click through.
- Click through fresh, then buy straight away. Start at the cashback site, go to Optimum Nutrition, and finish checkout in that same session and tab — no wandering off, no reopening hours later, no switching device.
- Only use voucher codes the cashback site lists. A code from anywhere else overrides the tracking link and voids your cashback.
- Give it time, then claim. Tracking can take a few days and payable cashback often weeks. If it never shows, raise a "missing cashback" claim with the site — keep your order confirmation.
