I am not really a shopping addict and I usually like to see and touch what I am buying, but I have just discovered two online shops that are really worth looking at: etsy and foof (this came from our friend Bijan who always finds out what's best on the web!).
Etsy - "Your place to buy and sell all hand made" - proposes a wide range of very nice accessories, all handmade by people from all around the world (check Morelle for Amsterdam based designer for instance). I fell in love with a flower brooch made by Monda (I collect broochs) and a very nice every day use bag by Morelle (I have too many but it's never enough).
All MacBook and iPod users should check foofshop ASAP! The cable turtles are really a must have, together with great MacBook and iPod sleeves. And if you still hesitate, here's another good reason to purchase from them: foof products are all ethically hand made in Australia.
