Allergy Test Cash Back Offers & Discounts

We're simply supported by sponsored advertisements 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 pass on 100% of this commission back to you as cash back which is actually paid by the retailer, then we'll make your cash back 'payable' to withdraw and spend.

TopCashback is completely free to use. We don’t take any sign-up or membership fees upfront or at any time from your account. Ever!

Cash back should track to your Earnings Page within 7 days of your purchase, but it isn't ready to withdraw straight away. We need to wait until the retailer's return policy is over before they can confirm your cash back, and then once the retailer has paid us the commission for your purchase, we'll make your cash back 'payable' and ready to withdraw.
