For those of you who are unaware, you can now make a 4 installment payment on any item on Gumroad through Zip(formerly Quadpay.)
On Teespring this can be made through Zip, Klarna, or Afterpay.
It splits the price of any item into 4 and you pay over the course of 6 weeks, rather than all at once.
You should do your own research as this is your money, but from what I understand this is all 100% interest free if paid on time.

Afterpay: Australia, New Zealand, United Kingdom, Canada and United States.
