PURCHASED  Wrigleys Doublemint - After a bit of hunting the very cheapest I could get any mints or chewing gum for was £1.20 for a pack of 7 (each containing 5 strips) in the (not a) poundshop.  Over my target price per item but necessary for the &quot;Emergency Kit&quot; part of the bag, I think.    Price per bag = £0.17
