M:How do you and your housemates like the new co-op? I’m thinking of joining it myself.
W:We like it quite a bit. We get some very fresh produce and staples and fair prices.
M:Does it save time?
W:Unfortunately, the answer is no. The co-op doesn’t carry everything. So we still wind up going to the supermarkets too, for cleaning supplies, batteries, that sort of thing.
M:I wish the co-op sold those items.
W:Well, I’ve been talking about it with some of the other members.
M:What do members have to do? Just pay a membership fee?
W:Yeah. There’s a fee and there’re meetings. But attendance isn’t acquired.But we do have to work there for an hour every week, which isn’t too bad. Once you are there you can get your shopping done.
M:I wouldn’t mind working there for some time. You’ll get to know about the products. But is the food free of additives? That will be the main reason I join. I’m a convert from junk food. Until now my diets have been largely chemical additives and pesticides.
W:Well, a lot of food is pure and pesticide-free. They also have vitamin supplements and soy and
tofu and that kind of thing. Lots of health food enthusiasts shop there. So if any source is health oriented, the co-op is.
M:I’d like to try it just for a month or so. Do they have trial memberships?
W:The shortest membership time is one month. Then if you like it, you can join for longer periods. And it becomes cheaper.A six-month membership costs as much as five individual months.
M:Sounds pretty easy. Maybe next time I run into you again it’ll be at the checkout line in the coop.
