Yes. there will be differences between your existing Buy Now, Pay Later (BNPL) plan(s) and any new BNPL plans you set up.
This is because you can be charged deferred interest on any plans that you set up on your Argos Card, but you won't be charged deferred interest on any new BNPL plans you set up after updating to Argos Pay.
To find out more about deferred interest, head to 'what's deferred interest and how would it impact me?'.
