After purchasing and using the Mac and iOS versions of 1Password extensively, I have found that I would love to use it on my Windows PC at home and work. I didn't buy the Mac/Windows bundle at first because I wasn't sure how I would like it. Now that I've switched completely over from the old password vault I was using, I would like to get the Windows version. But it would be super great if I could pay the incremental price to move to the bundle instead of buying the Windows version separately. Is that possible??
