the only advantage of the Secret Vault is that if you want for example, a Mega Tank, the Secret Vault offers a lower price than what the Mega Tank originally is. The biggest disadvantage of the Secret Vault is that because of the ramdom luck, you'll end up in spending more nanos and probably never get the unit you wished for
