Things to never buy (or only buy 'Used')

* Napkins - Always free when you buy food from a restaurant * Water - Buy a filter and be done with it * Desktops/Laptops - Unless you're gaming, you don't need that much power, and w/ the spike in prices, used offers the best bang for your buck anyways * DVDs - Use camelcamelcamel and set some alerts here. If you just want to watch it once, your local library might provide DVD rentals like mines does
