why there is no cheap grammarly accounts?

There used to be a Grammarly academic account that was on sale in this forum and others.

A lot of people were selling academic accounts for quite some time.

I'm not quite sure what happened to that program.

People are no longer selling such accounts.

Nowadays you can still see cheap Grammarly accounts for sales, but these are usually discounted versions.

Gone are the lifetime deals.

My company is lucky enough to have snagged one of those lifetime deals.

They do exist.

You probably would need to buy it in the aftermarket.
