I love MetalMart (southeast Michigan). We purchased 24 ft of 6061 2x1x.065 for around $57 this season. I don't know if they do shipping or what they would charge. They are familiar with FRC though, so there is that (the first time I wandered in this season they had the tax exempt forms all set and ready for the influx of school associated purchases).

Word of caution, their website triggers the chrome malware detector, and doesn't have particularly up-to-date info on stock anyway. I would recommend calling.
