This is why I hate going to the store. A simple trip for milk can easily turn into an expensive proposition. One thing that has helped lately to curb this costly trend is shopping for a list.
It never fails. I always forget something from the store which means another trip is forthcoming fairly soon. With a list, I buy what I need and nothing more. The best part is not forgetting something important. So far I spend less when shopping for a list and hopefully those more expensive trips will become a thing of the past.
