You're right. It isn't worth the effort. I used MasterPass a couple of days ago for the Newegg discount, and it isn't even a payment processor like PayPal or Google Wallet. It merely autopopulates credit card information on the store's site. I used a MasterCard with MasterPass, and during checkout I still had to authenticate my SSN and such with "MasterCard SecureCode." And even after having verified my personal information, MasterCard declined the charge as possibly fraudulent. What a clusterI bought the card for $39.99 without the masterpass. It's not worth $4 to me to sign up for an unknown electronic "wallet."
