How well does peanut butter keep before the jar is opened? I'd hate to stock up only to have it go bad before we use it all? Should it be refrigerated? We go thru about a jar per month...maybe not a huge amount, but I don't want to pay an arm and a leg for it.
I picked up a jar of Jif today. The use by date is 8/2013 so I think I'll head to BJs and pick up a year's worth by then the new crop will be in and maybe the price will drop.
