Website says "490 locations"
Branch local to me will sell to anyone, they accept credit cards or CASH


Branch manager didn't see any problem with an order for 12 feet,but he did say, "you might want to order an extra foot or so to allow for trimming as ends might not be truly square"
Hope this helps someone out.
