I have a double degree, B.S. Economics and B.S. Computer Science, however, my school did not mind me double counting classes, I just had to meet all of the requirements of both majors and accumulate 150 credits. Whereas a single degree would be just 120 credits. I could have received a double major, which is 120 credits (or more) and fulfilling all of the requirements of both majors. Since the CS program required 120 credits (with no wiggle room for classes that didn't fit the curriculum) adding on economics put me above 150 credits just to fullfil all of the requirements.
