I can tell you as a seller, I never check WTB
You're signaling to the world that you really want or need the item you're looking for. That gives sellers a clue to be aggressive with you on pricing. They know you want it, so they can upcharge. Always cultivate the illusion that you don't care one way or the other about items you want to purchase. You don't so much come out and say it, but the right attitude to convey is "Well, this is a nice item, but I don't really need it."
This advice works for women, too, btw. So, like, free bonus tip.
