Some recent sourcing experience--I am making some renos to my antennae and needed a couple of pieces of mill grade aluminum angle. During a recent walkthru at the local HD I noted that the material was avail---but I needed to make 2 cuts for my situation. The price was $88 + tax--and I would have to cut to length.
So I Googled for a local suppliers and came upon Boss Steel on Newkirk in Richmond Hill. They are a metal fabricator and retailer. The tab for my 2 pieces was $25 tax incl. ---cut to size. Ordered in the AM--picked up in the aft.
I ordered some more bits and pieces--similar pricing. Service was fantastic.
FYI--I have no commercial interest in Boss Steel and I dont think that any of my relatives work there rog
