I haven't seen anyone talking about this online store

There is this office and windows key store called esd codes and they sell office keys. They seem legit since they're affiliated with Microsoft and they have mostly positive reviews but I the description of every office key and I mean every has a note stating "if office (literally every single one) version is not available, you will receive the Professional Plus version at the same price" which they are trying to make it look like an upgrade but from what I searched the professional plus versions are bought in bulk by big companies and organizations and after they stop being updated they are being sold for cheap probably by employees. I have found multiple for less than 2 or even 1 buck and I feel they are scamming people.
