It is always hard to support the LBS even if they are great. It is just so hard for them to compete with online retailers offering much better prices. If all of the purchases i have made at my LBS were made online and all of the purchases i have made online were purchased at my LBS, I would have virutally nothing.
I don't enjoy giving them the end around but I enjoy watching my dollar go further. Also the fact that a LBS "has to make a profit" is none of my concern for the most part. The market place controls this, it is not my responsiblity to ensure they get a profit anymore than it is the LBS's responsibility that they never go out of business.
