MRPs have really very wide use and depends on your aim. I will give you a brief idea on the different possibility with concerned aim an trust you can make use of it to decide your best use.
1. MRP is a good way to get VP by purchasing 1TC. But, I would not suggest you to purchase high TC packs using it as it becomes loss. You can use MRP for this purpose if you are looking for some sales/purchase VP to achieve your rank. In other cases, it is meaningless.
2. You can convert these MRPs to nice products if you have hem in bulk amount. You can find the number of rewards available in exchange of MRPs in the rewards tab of TripleClicks. You just have to pay the shipping fee.
3. Another good way is to convert them into direct cash. This you can do by purchasing a product listed in your own store. This is a very secret tips but very effective.
Note: The value of MRP equivalent to Cash really goes high if you spend them in Bulk (around 15000 MRP) at a time. Unless, you may pay more for any product you purchase.
