Bottom line, none of these products are essentials to life. The price is either worth it to you as a buyer, or not. Thinking you lost money because it's later available for less is the same sort of faulty logic used by people who think they are "saving" money by buying something on sale (when it's an item they wouldn't ordinarily buy). I had a friend who used to do that all the time. We'd be at a store, and he'd see something on sale that he had no intention of buying before he walked in. He'd buy it, and congratulate himself on "saving" money. I'd point out "no, you just spent $50 that you hadn't planned to spend." He just didn't see it that way.
