Does it include the actual barrel, it seems a steel drum barrel like that is itself worth more than $20!

Wouldn't it be better if I store the oil for you and give you a certificate instead? You could buy it instantly and you could just email or whatsapp your christmas gift of coal...

Even better if the certificates are cryptographically signed in a chain and their custody is verified though a solution of the Byzantine generals problem.

No. You have to bring it back to the local supermarket or recycling center for the $20 deposit.
