If you want to use bitcoin to buy presents, the most obvious solution is gift cards, via Gyft or eGifter. The recipient will then be able to spend the gift card at one of a wide range of retailers.

You can pay for flights and hotels with bitcoin, through Expedia, CheapAir and Surf Air. If your ambitions are loftier, you can pay for space travel with some of your vast holdings, through Virgin Galactic.
