Cheapest MS Office?

[youngsyr]

Hi all, can anyone please advise the cheapest (legit) way to purchase Microsoft Office software?

I work as a self-employed contractor and have just picked up a new laptop, it has Windows 7 on it, but no Office software and I need Excel and Word (but not Access, Outlook or the other Pro software), preferably 2010 versions or later.

Thanks in advance for any help offered.
