how do amazon used booksellers stay in business selling many books for $0.01?
I understand that sellers have to play by Amazon's rules or be undersold. Do they make a small margin on handling? Are these free book stores staffed by volunteers? I'm trying to decide whether I'm taking advantage of someone by getting text books this cheap.

how did dial-up never be busy?
I have something that has been a noodle scratcher to me. Back in the days of dialup, I know people still use it, you'd dialup and the number would ring and answer. My question is, why was this number never busy? What crazy black magic was happening on the Phone Co. end that allowed this?
