If your pricing is firm, you love the game and you don't really want to sell. You're going to be hanging onto it for a while, most likely.
People love getting a deal, even if it's just a small amount. It will make the game sell faster. My wife used to list things on craigslist for the exact price she wanted to get. Everyone would ask her if she would take less and when she said no it wouldn't sell. I told her to ask $30 for an item she wanted to get $20 for. As normal, someone asked if she'd take $20 for it, she'd say yes and it'd sell right away. Same price, buyer just feels like they got a deal.
