I think that we all know what the word "fair" means. If you try to be fair with your local retailer then you are doing the right thing. If you know, or feel, that you are taking advantage of the local retailer then you may want to rethink your approach to buying equipment.

For me, the nearest good gear store is Summit Hut, in Tucson, about 40 miles away. Because of the distance, it is easier for me to buy on line if I know enough about what I am buying. If I need to look at an item, need to compare items, or need advice, I go to Summit Hut. If they are significantly helpful then I will buy the item from them. But, I will not let their clerks spend a lot of time with me and then buy the item cheaper on line. That is not fair.
