Note - I mostly wrote this before the above replies…
But why if it gives you zero benefit over making the purchase using your debit card? Potential reasons I can think of are:
- To delay actually making the payment for a month and keep a higher current account balance
- Similar to 1 - You don’t want to make the first payment upfront (and want the 3 instalments to start from the next payment date)
- To get points/ cash back
- The 0% for 18/24 months from a new card option (which I hadn’t thought about until @Revels mentioned it above)
Note: I’m assuming you don’t actually want to borrow money and will pay off in full with £0 interest - I also haven’t put S75 as a reason because I’m assuming that purchases over £100 can go on Flex…
Flex probably won’t be able to compete with 0% for 18/ 24 months but we’ve thought about if/ how it can cover some of the other points.
