Optimum Nutrition UK Cashback Offers & Discounts

We're simply supported by sponsored adverts and promotions dotted around the site and sometimes retailers will also pay us a bonus if we send a lot of shoppers their way.

When you make a purchase from a retailer featured on TopCashback after clicking through from our site, the retailer will give us a commission for sending you to their website. We share this commission with you when you earn money, which we call 'cashback' and is actually paid by the retailer. Then, we'll make your cashback 'payable' for you to withdraw and spend.

TopCashback is completely free to join, and if you opt for a classic account then there won't be any charges whatsoever. If you opt for a Plus account, then £5 of your annual cashback earnings will be deducted and you'll receive a range of additional benefits.

Cashback should appear on your Earnings page within 7 days of your purchase, but it usually isn't ready to withdraw straight away. We need to wait until the retailer's returns period is over before they confirm your cashback, and then once the retailer has paid us the commission for your purchase, we'll make your cashback 'payable' and ready to withdraw and spend.
