You'll never pay retail again...
There is NO "advantage" and you would not be accepted for conversion based on that reason.
If anything, you would be at a DISADVANTAGE because while non-Jews have to only obey the 10 Noahide Commandments, Jews have 613 commandments to obey and we get judged a lot more harshly than non-Jews (supposedly).
Furthermore, when you become Jewish, you become part of a "people", a tribe if you will. This means you will be part of the collective and have to look out for other Jews to help keep them from straying as they will do for you.
It's not easy to be a Jew...
