I have noticed that cans without ring puĺls are now cheaper, for that reason I suppose. Must be old stock, but I avoid buying, despite the lower price. Why is it that some tins can be opened quite easily with a strong hand opener despite my arthritic hands but others are impossibly tough?I have also had to throw unused tins away because the dratted ring pull snapped off .I have tried electric tin openers in the past but the generally break down. Why is corned beef only sold in stupidly shaped cans with fiddly openers which often snap off? Are they all sourced in Argentina? Beef is too expensive to throw away.
