I buy a lot of aluminum. A 5x10 sheet of 1/8 inch in Memphis was $315 last time I priced it. I can get the same sheet delivered to my house from Eastern Metals in St Louis for $167. I am not sure how far they deliver but they are the cheapest I have found. I do know if you are looking for small pieces ebay is a great place to look. I needed a piece of 6061 1/4 inch to make a custom hydrofoil on a lower unit. I found a piece already cut almost exact size I needed, saved me buying a whole sheet, cheap shipping too, Tight Lines, Adam Webb
