My LBS seems to offer pretty good prices. They list stuff mostly at the RRP but generally cut me some deals because I bought my bikes and assorted bits from them. They also do other odds and ends, like when I wasn't sure what difference bar ends would make and was reluctant to buy expensive grips with built-in ends without knowing, they gave me a used set to play with to see if I liked them.
It's also reassuring the number of times the owner has said if I want something he'll sell it to me, but he thinks I'd be wasting my money on it.
Anyway, Chain Reaction Cycles looks like they do some good prices - thanks for the tip. If nothing else it's good to know how LBS compares to what looks like a good cheap online source - from what I can see they measure up reasonably well so far. At least close enough that I'd rather pay a small premium to make sure they're around when I need them. CRC's site is down at the moment, I'll check them out tomorrow - thanks for the tip!
