Pay in 4 is a payment option offered by PayPal for orders between $30 and $1,500 based on certain eligibility requirements which are determined by PayPal. 

Pay in 4 will allow you to split your order total into 4 equal payments made every two weeks starting on the day of the original purchase. Payments are deducted automatically from the payment method selected in PayPal during checkout, although there is no penalty for paying off the full amount ahead of schedule.
