Your aunt buys groceries at four different stores every week. She has vented about the time- intensive search that may sometimes result in not being able to buy on sale items (i.e. out of stock). Her last experiences were unpleasant as she found out at home that some items were charged at slightly higher prices than the sticker prices (shown on the shelves), BUT it was inconvenient to return them to the stores! write a Recommendations for your aunt
