You'll be lucky. The retail price for Windows 8 Pro is $128 and Office is $144. Getting $272 worth of software for just over a quarter of the price ($80) is a decent offer if you ask me.
The lowest I'm happy to go is $70 and that's final.
I have windows 8 Pro if you are still looking. My original price was $30. I'm sure we can agree on a price. I can screen share and do paypal. Skype and/or PM me, i will pm you too.
