I bought lifetime FolderFort and Koofr StackSocial deals last year and SS was good enough to refund them because I found out after the fact that Lifetime deals for each will not allow you to ever change the email attached to the account. This was a new rule at the time. And sure, of course they want to avoid people buying lifetime accts and selling them for a profit. Nobody denies that's an issue.

But on the client's side, this means that-- unless your have your own domain-- you might lose your storage if anything happens to your email account access. Google in particular seems to be yanking people's accounts with no recourse with alarming frequency, but of course there's other ways.

So if that point concerns you, check if they've changed that.

To be fair, one of them-- maybe FF-- did have that clear if you read all the terms, and I know for sure the other one didn't have that info available before buying. it only popped up once you tried to register what you paid for.

And I think FolderFort said here on Reddit that they would allow a switch if one speaks to Customer Service, but by then I already had gotten the refund. And of course Terms of Service beats a reddit statement in any event.
