Meeting up with Mr Mark from the Bike Chain last night I confessed to having recently bought a pair of tyres from Wiggle. Guilt washing over me I started pondering why I went online instead of initially trying an LBS, which inevitably ends up in a list.
Online
Pros
Just order things from the desk at work
Being just a warehouse potential for huge stock
Which gives buying power and low prices
Cons
Returns are a pain, having to be posted back
Sometimes send the wrong thing
Can't get something in your hands to check it out first
LBS
Pros
That personal service
Getting to try things out (especially trying on clothes)
Getting advice on alternatives
Cons
Sometimes just difficult to get to the shop itself (time constraints and so on)
In some places the staff can be seen as a bit superior and off-putting, especially to a novice (though I was once told the type of brake I wanted most certainly wouldn't work with the type of lever I wanted, despite running the same setup on another bike for years previous)
In truth I'm getting a bit 'meh' about Wiggle (happened with ChainReactionCycles a long time ago, and I've only occasionaly dipped into SJS or Parkers - but I do love Hubjub, which is the closest to an online LBS I've ever found - just a touch niche for regular shopping).
Any more for the list?
