Honestly, I wouldn't put too much faith in this working. It's possible that I'm just really bad at this, but the last couple times I've been looking for work, I've never gotten a company to budge off their initial offer (even when I truthfully told them that I had 4 other offers on the table). In one case a company I turned down did come back with a higher offer a year later.
