I would recommend hunting for a genuine sealed package on ebay or something like that or buy a lifetime license of office 2021 from Microsoft or an authorized reseller for $100-150 (MS was selling it for $95 on black friday). Verified it with Microsoft and it was good. Finally bought an unopened package key of Office 2016 from ebay (physical package with a sealed key card) for $50. Sellers disappeared from eBay and Amazon.

I would pay more money for codes that work the first time or with online activation. This last experience, I had to get 2 replacement codes and still wasnt able to activate. And then, often, I need to get a replacement code.

They may work for a bit (anything between 1-4 months and then Microsoft will find and deactivate it). The Office codes never work with online activation and require telephone activation. Both were just emails from the sellers with the keys. Worked for 2 months and then MS deactivated it. The ones sold for $10-30 or being advertised as 'will email key instantly' are fraud. The only lifetime you can get it reliably are the ones sold with a physical package.
