It does affect the sale, so how to price without costing yourself anything? What an item's worth is what the market will bear, imo, as opposed to what it should be sold for. What think?
Btw, when I got home after buying something a week ago, the sticker on it showed a lower price than what I'd paid. That left a bad taste in my mouth. I understand that prices do go up, but I couldn't help feeling that I should've gotten it for less. I was totally fine with what I'd paid until I saw that "hidden" sticker. :) If I didn't know the person selling it to me, I would've decided to not buy again, or, buy with great wariness. Trust is an issue in pricing, imo.
