My father took the powder form chemicals we ordered at Adorama, and he got everything prepped at his house. Adorama was the only place that had everything (developer, stop bath and fixer) and more importantly was able to ship it. It came in two shipments. I believe two of them came in powder form, I think it was the stop bath which came in a small liquid container. He brought everything over this morning and we quickly setup to do a test run. He was concerned because he had never used a color enlarger to do black and white prints. The particular enlarger we have is able to develop both Black & White and Color prints.
