Bangalore: You can go to a supermarket almost anytime you want. Most of us love shopping at supermarkets, the core reason being we get a chance to fill the cart with choices and maybe get handed a free sample while shopping. And plus it is much easier when we shop for grocery at the local supermarket by getting sale items with coupons. There are certain items we pick when shopping at the super market because we run out of time to shop around in other places. But the fact is these items will just be more expensive than other shopping alternatives. If you are trying to save money consider not picking the following when you shop in a supermarket. Pet Food Many super markets now have a pet food sold at their stores. But shopping for your pet at a supermarket is not a wise idea. If you compare the cost of your pet food on a per-unit basis you may find that the 40-pound bag of dog food at the pet store is one-third less expensive than the 20-pound bag of the same brand of dog food at the supermarket. Pet food shouldn't be added in your list of items.
