There's a few ways that I am aware of to do this, all of which requires the converstion of coins to BTC. Here they are in the order of my preference:

1. Remitano.com (https://remitano.com/us?ref=jsfoo8)
2. Purchase gift cards for your favorite retailers (https://www.gyft.com/)
3. https://localbitcoins.com/

Hope this helps!
