I've NEVER paid retail for ANY of my bike purchases! I guess that's the benefit of living in a prairie town with few all terain bikers.
IE:
2002 Rocky Mountain Trailhead - retail $1000, paid $800
Shimano SPD 515 - retail $65, paid $50
Shimano shoes - retail $150, paid $115
Bike shorts - 20% off
Wifey's 2003 Kona Lana'i - retail $450, got it for about $440 with a set of Acera shifters to replace the stock grip shifters and a Kona bottle and cage thrown in.
Worst rip off I saw - Bow's Cycle in Calgary they were saying the Lana'i retailed for $475, they had it on sale for $450 (price on Kona's web site).
The only thing my LBS costs more for is Marz forks, the MX Comp ETA retails for about $550, they said they could do it for $470, which is still more than quoted on bikeroom.com ($400).
Edit - also forgot to mention my LBS does free tune ups on all bikes they sell for as long as the original owner owns it. If they replace parts they will charge for that. Compare that to the $70 bucks I overhead someone at The Bike Shop in Calgary pay to have his 02 Rocky tuned up.
