Work out how much it will cost you to pay it early vs how much it wuld cost you to let it run its course, if they're both the same, I'd pay it off early.
i second that, if both works out the same of course you should hold out until the end. its always better to have a bit of cash in hand and since the finance is not going to charge you extra in interest then why blow all the cash?
IF they give you a discount for settling the bill early then pay now.
