Can I haggle with the shop over price?

You can try, but don't expect dealers to be flexible on current-year models. Profit margins on bike sales are razor thin. It's not uncommon for a shop to net more money on the extras--helmet, pedals, computer, and so on--than on the bike sale itself. For this reason, dealers are often more willing to throw in a free seat bag or bottle cage than to give a deal on the bike.

Service is an area where you can seek out value: It's common for shops to provide a year of free basic adjustments on your new bike, so it's worth asking for this if your shop offers less.  Local bike shop will save you time and money in the end with service and any warranty issues. Shops tend to go the extra mile for you if they know you bought the bike there.
