what are your thoughts on women selling their positive pregnancy tests online?

I've been looking online at pregnancy tests ( trying to find a lot for cheap because ya girl loves testing) and I keep seeing used tests. First this blew me away and I think it's horrible that someone would use a test that isn't theirs to lie to a man or keep their man but at the same time maybe the women selling the test needs the money. So I'm almost at loss for words about this what about you?
