Safeway has HANDS DOWN the best selection for organic produce. (Veggies and fruit). Superstore has the best vegan/organic shelf items (rice, sauces, pasta, cleaning products and hygiene products). Hedley's Health Hut in the mall has a great selection of personal items as well as Two Farm Kids. However, I find those two to be a bit pricey.
Make up is tricky, best to find a good company like Arabonne (sp?) and a rep for advice.
Good luck! Stick with it and remember, baby steps are ok too
Every little change you make will add up! Some easy changes are white table salt out- pink Himalayan or sea salt in, white processed sugar out- organic cane in.
Also Tendercut butcher shop on 18th has organic beef, elk and bison if you are looking for meat at all.
