Bags of flour unopened and opened but expired dates (Townsend AL3)

I am now gluten intolerant and, sadly, cannot use these bags of flour.
One 1.5kg of plain flour dated Apr 2023 but is unopened and has been stored in a dry place.
I also have two opened bags of flour;
strong wholemeal flour half of 1.5k Jan 22 expiry
Quarter bag of self raising flour expiry Sep 22.
Please include name and when you can collect this weekend. I will only respond to these messages. Thank you
