- You spend your own money buying something for yourself—you therefore try to get the best possible product for the best possible price.
- You spend someone else's money buying something for yourself—you still try to get the best possible product, but you are not so concerned about the price.
- You spend your own money buying something for someone else—you are deeply concerned about the price, but you are not nearly so worried about the quality of the product.
- You spend someone else's money buying something for someone else—in which case, who gives a shit?
