I would say playing Eager Zebra Games....they offer more credits (MRP and Tcredits). Pricebenders is exciting and you also get rewarded by the system just for taking action, but the rewards compared to the Games, is less. EXCEPT when you win the auction naturally :)- if it is a product you REALLY want/need, the Auctions are great - but I will maintain that playing the Games REWARD you with more.....and it is FUN, informative, exciting....
