Hi, in my opinion and experience having a Standing Order of 125 TCredits which gives you the 1500 VP needed to maintain EA status is a good investment. You now have 125 Tcredits to use for bidding in Pricebender auctions which gives you 5 or even 10 Members Rewards Points (MRP's). Now with every 50 bids you do you now have the chance to get a PSA. And you can also use your Tcredits to play games and win prizes in eager zebra games.
Hope that helps.
