If I wasn’t paying close attention, I would have completely missed this one. At first glance, I thought that Target sold an individual pack of Cetaphil while Costco sold a twin pack.
However, upon closer inspection, I discovered that the Target was selling a 16 oz. bottle, while Costco was selling 2 x 20 oz. bottles. Anyways, Target sells Cetaphil Moisturizing Lotion for $0.559 per ounce while Costco sells it for $0.388 per ounce. If Costco sold a 16 oz. bottle at $0.388 per ounce, the total would be $6.21, quite a bit less than the $8.94 Target is charging.
