Any place to get a good deal on Microsoft Office (lifetime license) for two PCs?

[Moonbathing]

I'm hoping to get either Office 2019 or Office 2021, and I need it for two separate PCs.

I see a lot of keys on eBay for 1 PC, which are good prices, but I'm hesitant to buy from eBay because I've been told that the keys may not be authentic and could be revoked by Microsoft later on.

Is there any place to get a good price on MS Office and without fear of being ripped off?

I see them on stacksocial a lot. I bought it when it was 2 for $60. But I see them on there for 30-40.
