Trevor and his staff do a wonderful job of providing variety and quality. There are several subscriptions to choose from, including vegan, vegetarian, and omnivore. I have found that we have saved money on groceries, because we plan meals around our bag items, rather than randomly buying (usually too much) at the grocery store.
We opted out last fall to take a break, and I found I couldn't wait till spring came so we could sign up again. It's a great program!
