I feel bad about a lot of the things I purchase, considering where you put your money has a great impact on the world. I wish I would make more of an effort to purchase more local, homemade, natural things instead of corporation crap! Many companies out there support good causes and donate a portion of the proceeds. I DO buy some things from places that make me feel good such as American Apparel which is clothing made in the USA and sweatshop-free. However, not nearly enough.
I feel bad about not using enough natural and toxic free products like shampoos and cleaners. Again, I DO shop for natural shampoos, soaps, makeup, detergent, etc. here and there but not nearly as much as I want to. I still tend to go for whatever is more convenient/readily available.
