T.J.Maxx is a popular shopping destination for many Bostonians because it offers a wide variety of products at often discounted prices. It is almost like a routine for me to pick up some vegan snacks at the Allston T.J.Maxx on weekends. Every time I go shopping, I have the habit of collecting receipts to keep track of my spending. But last week, when I went to TJ Maxx to buy my favorite blueberry protein bars, I suddenly found myself unsure what to do when the cashier handed me the receipt. You may wonder why.
