It's really fun to shop in my favorite supermarket because it always have this bundle discount. Mostly food items like pasta, canned food and canned drinks, the items are packed in a plastic container. Computing the total cost of the items, the plastic container in effect comes in free plus some more discount of 5 to 10%. I usually buy the bundle with cooking oil since it is okay to put in stock for months. In my last shopping, the bundle I took was the tomato sauce with pasta and big Coke bottles. It is okay to stock up on food items that are non-perishable as long as you consume it before the end of the year.
