Newegg offers the OEM Parallels Desktop 8 for Mac, model no. PDFM8L-ROEM1DVD-EN, bundled with a Toshiba 8GB TransMemory USB 2.0 Flash Drive, model no. PFU008U-1ACW, for $29.99. This $25 mail-in rebate cuts it to $4.99. With free shipping, that's $24 under the lowest total price we could find for the software alone, although we saw this bundle for $3 less a week ago (since expired). It enables users to run Windows on an Intel-based Mac without rebooting.

Also available is ESET Smart Security 6 1-User for Windows, model no. 833691006507, for $19.99. This $15 mail-in rebate cuts it to $4.99. With $1.99 for shipping, that's $55 off list and the lowest total price we could find, although we saw it for $5 less last week (since expired). It's eligible for a free upgrade to version 2014. Both rebates end March 24.
