Sportsbook.com and their family of books have a limited number of props you can parlay for the Super Bowl every year. There are usually approximately 20 listed and they are pretty standard....first team to score, time of ist score..etc. Not sure of any others on-line that offfer parlays on props.
Many sportsbooks in Vegas have parlay cards for the Super Bowl each year and you can find value if you get them early enough.
