Is selling a personal item on Facebook considered spam?

[Jack]

I'm looking to sell a tablet computer and I thought posting it on Facebook might help. Everybody I'm friends with on Facebook are real friends, so I'm not some stranger they don't know. Also, I'm selling it at a good price, so I bet some people would be genuinely interested. But am I "annoying" others by making posts to sell stuff? I've never done this before so I'm not bombing them with advertising. I've seen others make posts to sell stuff, but I don't want people to think I'm taking advantage of them and using friends/family as potential customers. Most people get on Facebook to see what others are doing, not to use it like Craig's List. But I figure that just this one time won't really matter much.
