Have enough credits for price benders auctions. Check to see what time for any special auctions to start. Make sure to record your email or sms to remind you when auctions start. Don't get in too early because it takes so long to finish. Not only that, but your credit will run out quickly. Try to get into your bidding once you know it's nearly finished or not getting hardly any bets. Even though you don't win anything, you still get more MRP points.
