When you shop at online retailer BlueFly, your purchase is shipped to you in a bland cardboard box. Inside, however, is a smooth, elegant paper shopping bag with ribbon handles. Just as if you had trotted home from the boutique, how delightful!
Preserving that physical evidence of buying something in the real world really completes the shopping experience for me in the online world.
