Organic produce usually costs more, but it doesn't mean you can't save on pesticide-free fruits and veggies if you just shop differently -- specifically, shop later in the day. Since produce, both conventional and organic, is perishable, supermarkets often mark down prices in the evening hours when foot traffic is slowest. If you time your visits right, you can save up to 75 percent off organic produce.

When is the best time to give the bathroom a good cleaning? Right after you shower. Surfaces in the bathroom -- like mirrors, faucets and countertops -- will likely have a fine layer of steam on top of them. With just a microfiber towel, you can wipe down all the surfaces quickly. And the grout in the shower? All the grime and dirt is considerably looser after a hot shower; just scrub and rinse in minutes.

Here's a simple way to clean up a dirty secret in the shower: Choose bar soap over body wash. Liquid body washes are packaged in plastic bottles that, even if they are recycled, are still made from petroleum sources. Also, the No. 1 ingredient in body wash is water, which adds significant weight to the package, requiring more fuel to ship it from the factory to the store shelves. Even if the body wash is an all-natural or organic brand, bar soap has it beat as the greenest choice.
