Just one little item I've been thinking of mentioning for awhile. They don't sell bicycles or even frames but for the parts they do sell, Mountain Equipment Co-op has the best prices I've ever seen. My most frequent purchase there is tubes for the old 10 speed tires, 27 X 1 1/4 inch. They have been $2 for about 5 years now. I don't go there very often and pick up 6 to 10 at a time. A 5 gear Shimano rear sprocket was $8.

They don't even have frames or exotic parts, but for basic tools and everyday stuff they are really good.
