Getting environmentally friendly items in bulk

One of the problems with organic and earth-friendly items is that they rarely come in bulk. Since these items usually have a premium associated with them because they tend to be more expensive to manufacture, buying large amounts at once can help offset the price. The internet fortunately provides:

• My favorite shampoo comes in a 32 oz version, which is good.
• I found an all-purpose cleaner that does many jobs in one: Simple Green . You don't have to buy this one off the internet either: you can pick up at Home Depot, Lowes, and Sams Club for about 10 bucks. This can be diluted and used to clean almost anything (even laundry) so it will see a lot of use.
• Regular liquid soap (organic) can be bought in bulk too.

As it turns out there are many bulk organic items. I also found out that you can make your own cleaners from baking soda, vinegar, and other items, which is pretty cool.
