What account is affected in an account journal when you return office supplies that was bought on account?

Say I purchsed $500 in Office Supplies on account, I return the office supplies, since I purchased them on account, the company I purchased them from will extend me a credit to my account decreasing the balance I owe them by the said amount. My books will record....

Account Payable (debit)

Office Supplies (credit)

I debit my Account Payable to show that I no longer owe that amount and I credit my Office Supplies to show that I no longer have that amount of supplies on hand.
