Once you've made a purchase you should see your cashback track on to your activity page. You can see how long it will take for your purchase to track on each retailers Quidco page under 'Tracking Speed'.
Your cashback will then await approval from the retailer. This can take 3-6 months depending on the retailer, but please do check the estimated payment dates on the retailer's Quidco page.
You may also see an estimated payment date appear on your activity page once your payment tracks in.
Once the cashback is approved by the retailer, this will update to the status 'confirmed' and be moved over your payments page for withdrawal.
