I'm not a member, but a farm I patronize at the market has 10-week seasonal CSAs for $225 vegetables only or $325 for vegetables, meat and eggs or dairy. They say that "Each basket will provide produce for 3-4 people per week."

They do describe sample baskets just as you say. Their most recent offering lists as follows:

A Sample Basket

Purple Haze Carrots
Royal Burgundy Beans
Toscano Kale
Parsley
Green Onions
Lettuce
Cucumbers
Basil

An Omnivores Basket would add:
1/2 Dozen Eggs
1.5 lb Ground Beef from [another farm]
Could you visit the farm on pick-up day to see what current subscribers are getting?
