It really depends on pricing. The more expensive the service, the more likely there's negotiating fat explicitly build in. Two jobs ago, I was with a company that sold medical equipment mostly in the 4-5 figure range. They had a flat 5% discount that the sales guys opened with.
Similarly, having just implemented ethernet-over-copper for our office, I got to see more fat in action there. It's ridiculously expensive here in aus - I got a 5% discount just by asking "is there a discount?", and our CFO finalised the deal and got a 5% discount by asking the same question again. Neither of us are hagglers - that fat is just built into the price.
On the other hand, if you're doing consumer-level stuff with many users, individual discounts would likely be a headache and usually people hung up over a once-off couple of dollars are more trouble than they're worth. Highly contextual on target audience though, methinks.
