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 Extension and our Slickdeals 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.
We'll be working on ways to make this messaging clear if and when we detect that another application has taken credit for the transaction before you complete checkout, but your best bet is to make sure you're only running the SD Extension if you're specifically looking to receive cashback from our program.
