There are a few things that may prevent you from being eligible for cashback :
Where a gift card or shopping card is used in payment of the purchase
Where a voucher or discount code not published by Quidco is used
Where a gift card, voucher or postage stamps have been purchased
Where a purchase is cancelled, returned or amended
Where the order is not completed wholly online in a single visit to the retailer
Where the retailer’s terms and conditions for cashback have not been met
Where another referrer is awarded the commission for the sale e.g. comparison site, rewards site, search engine, etc
