Costco vs. Sam's Club (in my opinion)

I used to be a Sam's shopper and now since we have moved after much contemplation we have changed over to Costco. I must say that I am much happier with the products they carry. The crowds are annoying but as long as I have Jared with me they don't seem to bother me as much. They have many of the same or comparable items with not much of a price difference.

They carry a lot of natural / organic / better for you - products that Sam's just didn't or haven't yet. Here is a list of the things that I have noticed and / or purchased so far: milk (cow and soy) butter, eggs, juices, fruit, breads, fruit spreads, peanut butter, pasta, pasta sauce, and laundry detergent* (which so far I love) turkey bacon, breakfast and dinner soy meats, fruit leathers, nuts, chips and all kinds of goodies that we love.

The only thing that I wish they carried that they don't yet is organic / natural paper products and beef, but I guess either they don't come in bulk yet or there isn't a high demand for them. I wonder if after they start releasing the "cloned" meats if the sales of organic beef and dairy products will rise, or are we just all destined to be science experiments?
