For those of us that pay bills, we still use stamps. This affects people in the US, not Eurpean countries. USPS is still going strong.
I know the average age here on Computer Forums is like 15 or so, which is why it's hard for you "kids" to understand yet, but one of these days when you guys live out on your own, you'll see what I mean when the expenses pile up and you are forced to pay for them one way or the other. Either you use stamps or you pay for all your bills online. I hate the online idea because my whole life would be in cyperspace. I don't mind buying stuff over the Internet, but bills I generally pay in person or by mail. By mail most of the time. Easy to do. I don't know how people in Europe pay their bills, but that's how we do it in the US. I remember the days when postage use to be 25 cents.
