If you want your digital planner now, but want to split the cost over time, you now have that option through PayPal. Through a new service PayPal offers, you can make an online purchase and then pay it off in four bi-weekly installments. PayPal said this doesn’t impact your credit score and there is 0% interest. 

To use this Pay in 4 service, you must have a valid PayPal account connected to a credit or debit card. When you check out, look for the “Pay Later” button under the PayPal checkout option.
