Newegg offers Bitdefender Sphere 2013 for PC, Mac, and Android, bundled with the Toshiba TransMemory 8GB USB 2.0 Flash Drive, for $65. This $65 mail-in rebate cuts it to $0. With free shipping, that's better than last month's mention (which lacked the flash drive) and $64 under the lowest total price we could find for these items purchased separately elsewhere. It can be installed on an unlimited number of devices. Rebate expires February 6.
