So, I know that I have referenced Drugstore.com several times, but I thought I would post on it. I have really gotten hooked on it! You get free shipping over $25.00. Their prices are usually better than Target, and it's very convenient to have them shipped right to the doorstep. They also have a "list" function which is quite nice. So that when you want to re-order commonly ordered items, you can do so easily, without having to re-search for them on the site.
They also have customer reviews for the products, which have thus far been quite informative and reliable.
