Mistake #2: You are not familiar with where the items are being placed.
This is a very good example of familiarity. You will be an effective grocery shopper if you pick one store to go to for your grocery needs. If you have a familiar store to visit, then, everything will be much easier for you – believe me.
Now, as you have already decided which store you will frequent, the next step is to get used to the aisles and where the common items you buy are placed. For the first few trips, it will be familiarizing with the place. After that, you’d be a pro.
