Flour products (Uxbridge UB8)

I have developed a gluten intolerance so I have these flour-based products to give away: unopened strong white flour, 2 unopened multiseed bread mixes, unopened matzo meal, nearly full strong white flour and less than half-full strong wholemeal flour. They are mostly past their sell-by dates but look fine although the age might affect the yeast in the bread mixes.
