OPINION OF THE COURT

On summary consideration, order affirmed, with costs. We agree with the Appellate Division that plaintiff was entitled to recover a monthly service charge on the balance due and owing to plaintiff for goods sold and delivered in accordance with the express agreement of the parties. Furthermore, we cannot say that the court abused its discretion as a matter of law in permitting plaintiff to discontinue its second cause of action without prejudice.
