Mid South is still allowing backorders of powder. I'd put in a backorder there and cancel it if you happen to find it in stock somewhere else in the meantime. I just received 3 8# jugs of H4350 that I had on backorder with Mid South for about 12 weeks. During that 12 weeks several other vendors had occasional stocks pop up but had either 10# or 8# limits-- I wanted a larger quantity all from the same lot so I just waited for my backorder.
