I purchased a bulk pack of 6* multipack of Walkers crisps sometime back. They were in date of purchase and a mistake I made was not noting down the Expiry date before putting them in storage. I've now taken them out, and since discovered they expired on the 26/09/2020. I've read that they can last between 2 weeks to 3 months after BBE. I have over 90+ individual packets remaining and I'd rather not throw anything away.
