I have recently become more proactive at looking for the clearance items sections when I visit various stores including grocery stores, pharmacies, and even clothing stores. Whether it be due to upcoming expiration dates or a small insignificant amount of damage to clothing, many retail outlets have a clearance section that allows their customers to buy products at a deep discount.
If you want to save money when you shop, I recommend that you check out the clearance items first before being willing to pay regular price for any items you need. For example, the other day I stopped by a pharmacy to fill a prescription and discovered that a high quality body wash was priced at under $1.50. A brand of shampoo I like was about 65 cents, and so on. So, I stocked up on some items that I know I will use for a fraction of the price.
