You could always give a Kiva.org card where your friends could invest in a business in a developing country. With their interest paid back, they could spend it on anything.

Love the idea behind these charm necklaces. $75 each, but the charms bought go towards helping build homes!

I think the smart boxes can be fun too! A bit more pricey but they are gifts that can be enjoyed for two between friends :)

This is a great place to find a wide variety of gift cards. Canada's first online marketplace dedicated to the exchange of gift card. Buyers can save through buying discount gift cards. Sellers have more flexibility to exchange their unwanted giftcards for cash.

Artsicle just released gift cards, which would be perfect for your art loving friends. They can choose an original piece by an emerging artist to rent for a month (or longer, depending on what size card you buy). You can send an e-card or they'll mail a fun little box (for free!).
