Navneet Joshi this is really a good question which I am sure not a lot of new users are sure how to answer.
Personally I think a great way to use your MRP is to save and save and save, when you have saved up enough points you can use it to buy Ipad's, camera's etc.
If you can save and buy enough of these goodies then you might also be interested in re-selling these goodies and earn even more money.
Hope this helps.
All the best of luck to you.
