Bold negotiation tactic. I'm a fan. I've often found myself at Best Buy explaining that I'd gladly buy a new computer if they can ship all of the hardware components to me for free and I'll assemble them myself.

That way, Best Buy doesn't make any money and I spend hours of my day (which, by the way, I bill my employer hundreds of dollars per hour for during the work week) assembling something that I'll have to do all the maintenance and upkeep for myself! Everybody wins!
