M: How do you and your housemates like [5] 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. [6] 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. [7] 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. [8] 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 co-op.
