Hunt for Laundry Detergent Ingredients in Vancouver

I started the hunt for ingredients for my homemade detergent experiment today. I found Borax at Safeway ($6.49 CDN) and London Drugs ($4.99 CDN). Safeway also had washing soda by Arm & Hammer but it smelt like it was perfumed which I’d rather stay away from. No luck finding Fels Naptha Soap yet. I did find some Sunlight bar soap at Safeway that would work but it came in a plastic package that couldn’t be recycled or composted so my hunt continues. I think I need to find an old time pharmacy as the mainstream ones only carry Tide and it’s competitors.
