I'm proud to be a member of Willy St Co-op.
I'm not a huge organic person, which means that generally I will go to regular grocery stores to do my shopping, because I don't want to pay the markup for organic. I do hit up willy st about once a month (I travel a lot).
I love Willy St for their:
* produce (expensive, but local, high quality)
* bulk section (giant cous cous, fair prices)
* juice bar (just found out about this gem)
* dairy/eggs (great local section)
I think the meat department could use a little enhancing, but there are a lot of vegetarians that shop here.
