I generally agree with most of what Francis Storrs wrote in “The Fickle Food Shopper” (October 14). I do go to several markets according to what is on sale. What I do not do is go to Stop & Shop. I do not like loyalty cards, and I do not like having them track my habits. When the Stop & Shop in my area went to cards, I went away and have stayed away, even though it is the closest large market to me. I go to Roche Bros., Crosby’s, and Donelan’s, generally in that order of preference. None of them requires a card to get specials.
