I got an email about a new site, www.soap.com (it's a sister company to www.diapers.com)
They sell any household item you can think of - mascara, laundry detergent, condoms, toilet paper, toothpaste, everything! From what I can see, the prices are pretty comparable to prices in the stores. You get free 2-day shipping on orders $25+, so it sounds pretty convenient to have it shipped to your front door!
Give it a try, let me know what you think!
