We love grocery stores. Their stock and trade is food — fresh, frozen, canned or prepared — and kitchen staples like paper towels and laundry detergent. But there are a whole host of other items that cost a premium in grocery stores because of the "convenience" factor. You can get them cheaper at a discount department or hardware store, dollar store, or drug store so leave the following items off your shopping list:
1. Cookware and Kitchen Utensils
2. Cosmetics, toiletries, and personal care items
3. Small appliances
4. Party supplies
5. Batteries, light bulbs, extension cords

biasanya mereka mengenakan harga premium pada barang barang tersebut
kalo menurut ce cek i sih, kalo supermarket/toserba itu mengenakan harga premium pada barang2 yang hanya sebagai pelengkap saja. maksudnya barang yg ditujukan biar kelihatan lengkap aja tokonya :P kek semacam barang elektronik, kosmetik de el el segala macam.
