I go shopping and I notice one thing. I always come back with something. In most cases, it is stuff that I can use. There are times though when I buy stuff and I find out later that it is a piece of junk. For example, I bought a bluetooth headset for $20. After the battery ran out, I tried to buy another one. An AAAA battery. This battery could not be found in any store. I gave up and paid $100 for another rechargable bluetooth. Sometimes, it is better to pay more for an item that you need or want. I will remember that next time.
