2. Cooking sprays. For as long as I have been living and cooking on my own I have been buying off brand cooking sprays. When I ran out of my Giant Eagle brand spray, I decided that since I am baking for hire I would try Pam cooking spray. I have to admit that I'm pretty blown away by the results. My cakes are popping right out of the pan and the pan looks so clean you can barely tell it was used. I will probably keep a can of the cheap spray around for day-to-day cooking but for baking it's Pam all the way.
3. Pop. I call it pop. You might call it soda but regardless what name it goes by, it needs to be the name brand. Off brand pop tastes flat and I think it has a weird spiciness.
4. Tennis shoes. Buying name brand shoes is probably smart in general but I know from lots of experience that you get what you pay for with tennis shoes. Good tennis shoes get broken in quickly and seldom will they give you blisters or rub your feet raw. Your feet hold your entire body up so treat them right and invest in a good pair of shoes. I also suggest you go to a shoe store that will help you find the right shoes. I like Front Runner. The sales person helped me pick out the right shoe by analyzing my shoe patterns and watching me run and walk. It was very helpful. My favorite running shoe is made by Asics.
What are some items you insist on buying name brand?
