Hi does anyone know how to use klarna in store (e.g smyths superstore). I've recently been accepted for a physical klarna card that I've received in the post and wanted to get some bits off it for christmas (no judging please I can very much afford to and know what I'm getting myself into). I just don't understand how it works I've searched everywhere and there's nothing that says black and white what you need to do when in store I don't want to get to the checkout and look like a numpty. Do I need to do something on the app first? Do I need to add money into my account (I want to do a pay instalments)? Help please thank you!!
