This exact card is available @ RADIO SHACK for $49.99 until 11/10/2012.
However,if you sign-up for their deal alerts, newsletters, etc.....
you may find a $10 off any $40 purchase in your spam folder, as I did.
I was having difficulty w/the website accepting the coupon code, as I was put in a continuous loop of check-out/shipping information, etc..... so I paid the local RADIO SHACK store a visit.
They ordered it direct-ship to me free of shipping costs & was also successful in applying the $10 discount.
Bottom line for the SANDISK 64GB ULTRA CLASS 10 MICRO SDXC CARD : $39.99 + sales tax.
