I got a deal on my last two new bikes, both of which were special order.
Having said that, I was on the informal "preferred customer list" and had a good relationship with the owner. Furthermore, I told him I wanted the bike first, then asked what he could do to help me out, so there was no haggling involved per se.
Now I work for a shop, so I will be able to EP my next bike. Muahahahaha!
