Before you purchase an item at the local grocery or drug store, google search the manufacturer! I had run out of contact lens cleaning solution, so I ran a search online for my preferred contact lens cleaning solution (Opti-Free) and the word “coupon”. I was able to find a $2.00 coupon from the manufacturer! Combine that with a store coupon and you can cut the cost close to 50% off. I now do this for all items such as toilet paper, toothpaste, etc. If you are unfamiliar with the manufacturer or do not have a favorite brand, be sure to google search different brands before combining with the word coupon. I did this with Olive Oil.
