To collect points on your transaction, you do need to ensure that you have clicked through from your Rewards4Imps account and then complete your purchase immediately and wholly online.
If you do forget to click through this means that there is no click record on your Rewards4Imps account to confirm that your transaction started from the Rewards4Imps website. As such, we are unable to raise a missing points claim with the retailer and will not be able to recover any points.
