Microsoft Windows 7 Home Premium 64-Bit Full Version for $99.99 shipped, along with a $20 Newegg Gift Card. Here is a screenshot for reference. This comes in OEM full version that does not require prior ownership and does not come with a pretty retail box. You will also need to do a complete clean installation rather than an in-place upgrade, but the software itself is identical. Here is more information about OEM software.
