It’s easy for Overstock.com to become the only object of one’s obsession. Need some olive oil? A new outfit? Or perhaps an ornithological book about owls? Okay, I’ve had …enough fun with my O’s. Overstock.com is a place where you can find practically any item from A to Z. Think of it as like the virtual version of thousands of diverse stores packed into one place. It was one of the first major online retailers when it was launched in 1999, and today it continues to be opulent, orderly and even otherworldly. Wow, I really can’t help myself.
