Soap is a site where you can order just about anything, it's kind of like Drugstore(dot)com only better. You can order toilet paper, paper towels, and all kinds of other stuff sold at CVS and other pharmacies. They also have tons of hair products, including natural products, so don't forget to check out that area. But my favorite things to order are the large things of toilet paper and paper towels and heavy things like Tide so I don't have to worry about carrying them from my car into my apartment. Sounds lazy right? But it's all about convenience for me. Shipping is free over $25, there's no waiting in line, the prices are good, and your purchases arrive fast.
World Market is another great site for home decor. I just purchased an awesome lamp for my apartment, it's unique and fits in perfectly with my decor. You can get really great pieces from all over the world, your home will look like you've traveled all over the world collecting pieces. Plus, the prices are fair.
UGallery is another unique site. Artists showcase their art work online and you can buy directly from them. For me art is all about finding one of a kind pieces that you love. Instead of going to Pier 1 or Ikea for art that tons of people will have you can spend around the same amount of money buying something unique from an up and coming artist that just might be the next Picasso.
