124th Corner Dollar Discount

I went to the store to get 1 can of pie filling. After looking through all the pie filling best before dated I realized that they were ALL past their date. It is April 9, 2016 and their closest date was January 9, 2016. Some of the cans were from 2014. I brought the January can to the register, it had a $1.99 sale sticker on it. I told the cashiers that all their pie fillings are expired. I told them I would give them $1 for the one I had. They demanded full price else they wouldn't sell. They were quite rude about it.
