you can use a saving account it usually has no issues
If you make need more accounts after that you can always add more chequing accounts to your existing bank accounts
its like your bank account usually comes with a chequing and saving account
you can then add more chequing accounts .so say you had 2 chequing accounts,the new ones will have their distinct account numbers and can be used for separate amazon accounts
but the additional 2 youre adding will be relatively fast because you already have an account in the bank
