I did by accident. I was at Aldi on Tuesday and the manager was marking down their chicken breast--$2 off each package. I bought four packages (3 lbs each) for only about 60 cents each! I would have bought more, but I didn't want to seem greedy. He said that he always has a special on meet to sell quickly before his truck comes on Wednesdays. You can be sure I will make Tuesdays my Aldi shopping day!
How about you? Have you ever asked your store's butcher when they mark down their meat?
