Neither of my parents were known for spending money. They both were more than happy to see Wal Mart come to town with it's generic of everything.
I can remember vividly the lesson I learned when I was about 12, spending the summer with Ralph and Lois and we went to the grocery store. He sent me to find a jar of peanut butter. At the time, I was like my niece Gracen, peanut butter was the only sustenance.
I came back with the store brand and put it in the cart. Ralph looked at it and said, casually, if you are going to buy something don't waste your time with that junk, go get the good stuff. I was more than happy to do so.
