It was not disclosed in the product description that the batteries were past their expiration date. They did not work and I was told by customer service that I had to bring them in to a store to notify them there. The customer service representative never offered me a prepaid return label. One of the multiple envelopes that my order arrived in had packs of electronic game stickers enclosed instead of batteries. "An honest mistake", I was told by customer service!!! I'll leave that decision up to you, the next potential Bestbuy customer.
