I live in Canada, so I'm not eligible for that discount. Wasn't there a Home Basic that was even cheaper than Home Premium?
Cheapest price in Canada that i know of OEM version.
Microsoft Windows 7 Home Premium Edition 64BIT Dvd Oem http://www.directcanada.com/products/?sku=12850SW2113&vpn=GFC-00599&manufacture=MICROSOFT
Microsoft Windows 7 Home Premium Edition 32BIT DVD OEM http://www.directcanada.com/products/?sku=12850SW4444&vpn=GFC-00564&manufacture=MICROSOFT
Home Basic is for emerging markets only and not generally available in the Western developed countries.
Windows 7 Starter is lame and not worth it imo.
Home Premium is all most people need just remember MS is sneaky the way they package it.
I've read of many people downloading or buying retail thinking they were getting the 64bit version only to discover that wasn't the case.
