I think MRP is the most useful for me at the end of the month. If I am running a little low on sales VP, I can use my MRP to purchase single TCredits that will help me to maintain my BTL status. It also allows me to save up my MRP for anything that I might be looking to purchase in the future. I purchase 125 TCredits monthly. I only play double MRP auctions, therefore I earn 1250 MRP a month, and I only spend 500 MRP to cover my sales VP. Saving up for the IPad:)
