You are not able to get cashback from more than one extension / app. If you are a user of multiple cashback extensions, we recommend disabling them when making a purchase using the Slickdeals Cashback Rewards Program.
Please note that it is not possible to 'double-dip' and receive credit from two different cashback programs. Your order will only ever be attributed to one of these programs, so if we don't ever receive a record from the retailer and you had another cashback extension running, chances are the credit went outside of Slickdeals.
