Can I pay off my layaway plan at Sears before the scheduled date?

I put a stand mixer on layaway at Sears. They gave me scheduled payment dates and those end in September. I don't need that long though and should be able to have it paid in a couple of weeks. Can I make payments before the dates or do I have to pay every 2 weeks like they ask?|||Yes you can! You do not have to make minimum payments as it shows on your statement. Also paying it off early will save you money. (finance charges)|||You can pay it off!|||Yes you can.
