I installed Google Wallet on my Galaxy Nexus immediately when I got it. I used the 10$ pre-paid card that I received the first time I activated it. Approximately a week later I exchanged my Nexus for a new one due to the dreaded "banding" or "streaking" on the screen and immediately installed Google Wallet on the new Nexus. Upon opening and activating Google Wallet again I got ANOTHER 10$ pre-paid Google Wallet MasterCard! Has anyone else experienced the same thing?
