Thanks for the question about MS Office 2010. I didn't see anything on your list to make a trade, but I don't know if you have paypal or giftcards?
I just checked and I only have the Pro version now (sorry need to remove the other one) It's a PKC key and will activate office pro, so its a single use key (only one activation). I have a similar key and I've uninstalled office from a pc and used the key on another pc and activated with no problems.
I also have an office 365 subscription key for 1year (works on up to 5 devices - pc, mac, iphone, and I think android phones)
Includes
Word
Excel
PowerPoint
Outlook
Access
Publisher
OneNote
for 1year. After that you can renew the subscription.
