I purchased my Giant bike from my LBS...they were great...took $35 off the original price,, patient and offered to tune up the bike in a couple of months free of charge. I have purchased a few accessories from them...Topeak rack, mirror.etc.

Now here is my question.... do you or would you feel guilty returning to the LBS with new or additional accessories attached to you bike that you did not purchase from them? ...I bought a Topeak Trunk bag and other items online...the LBS had an Airzound horn for $45. I got it from Amazon for $19.00!
