As our machines are new, we are able to offer you OEM versions of Office which are upto half the price of the retail versions. Dont worry, any new machine that comes with office is the OEM version - it has all the same features and programs but Microsoft offer a discount when they are installed to brand new systems and the OEM (us) can confirm it is indeed for a new system. As they are OEM in other words "media less" you will need an operating systyem from us in order for us to preinstall it for you otherwise we will simply supply the licence which has the official Microsoft link to download and install it once your operating system has been installed.
