Being able to buy in Installments

Some Peoples from other countries probably can't pay the full price due their currency being devalued or because they're paid by month and not by day/hour, and paying by installments just helps them to get a product by using the reserved money for that month, like, if the buyer pays for a 300 USD product but they only have 100 USD left to buy anything each month, they can pay 300 USD in 3 months , by just using the Installments on their credit card
