I can see using these gusy if they are the only outlet for the specific products you want in your area, but there is little or no incentive to those of us that live in better serviced areas to shop there.
Their prices range from high to ludicrous, and just about everything they sell is available as good or better from local markets, specialty stores or farmer's markets in my area. I know that other areas may not be as well served by their retailers - we are lucky in Vancouver, a foodie haven with reasonable prices.
