You can pay, but the content is delivered to you. It is not transferable to another account.
You can make the payment, but what you buy is delivered to you — to the email you paid with, or to your account.
Not transferable
Purchases are not moved between accounts. A Membership belongs to the account that bought it, and a paid file is delivered to the buyer.
Why
Every purchase carries a delivery record, and that record is what resolves a dispute and what proves the content was received. Moving a purchase between people breaks the one thing that protects both sides.
What you can do
Share the creator's link. Anything on this platform can be bought as a guest or with an account, so there is nothing standing in the way of someone buying it themselves.
Piggy Pots
A Piggy Pot is the closest thing to buying together: several people buy into one content product, and everyone who contributes receives it.
