What is the best use for MRP ? I would say trade in your MRP use for purchasing digital items from tripleclicks while gaining 1 single TCredit which you can use in pricebenders as a single bid in the Daily auctions and earn 5 or 10 MRP!
Also use your MRP to buy 2 single TCredits for 126MRP each,(total 252MRP).
You will have earned a Grand Total of 30VP from 30bids equals a Grand Total of 204VP for buying 2 TCreits.
