I don't know how I managed it, but I've got a bag and a half of Harrisons that are dated for Aug 2011.

How strict do you think their use by dates are and should I chuck the lot out? it seems pretty wasteful, especially when money is tight. and Sam has been eating it for two weeks already- I didn't think to check it. i've never had it go out before= usually gets gobbled too quick!

Thanks
