Is there a catch to PayPal Pay in 4?

So, let me get this straight. You're offering this PayPal Pay in 4 service where customers can split their purchases into four equal payments with no interest. That sounds like a pretty sweet deal, but I have to ask – is there a catch? Are there any hidden fees or conditions that we should be aware of before signing up for this service? We don't want to get stuck with any unexpected charges or penalties, so it's important to understand all the details upfront. Can you please clarify any potential drawbacks or limitations of the PayPal Pay in 4 service?
