Yes, you can. I couldn't post a pic of my iRazoo winnings because it shows the codes for the gift cards. I have gotten plenty there though. Thank you for using my link.
Another good site is points2shop. I can no longer use it due to my satelitte internet changing IP addresses on me but I did make over $100 there in a short period. With them, you can order anything on Amazon - except ebooks - with your points rather than cashing in for gift cards.
