Increase your odds of winning something. I find it difficult to win the big contests, you know the ones that are advertised throughout the supermarket for Chinese New Year, Hari Raya or Deepavali. Because those are contests everyone enters. If you only enter 1 contest, chances are its the big one right.
Contests that allow for redemption are definite wins! Contests that offer multiples of the same prize increase your odds. Instead of 1 big prize, they offer 25 winners the same prize (e.g. electric steamer). I do win such contests fairly often so I can attest it is more attainable.
