What has to be paid in for shipping unless otherwise requested?

In the context of shipping transactions, the requirement is often for payment to be made in cash, specifically in US dollars. This is typically the default method unless there are specific arrangements or requests made otherwise by the parties involved in the transaction. Using cash is conventional due to its immediacy, which allows for straightforward confirmation of payment, reducing the risk of fraud or default that can sometimes be associated with other payment methods.

Credit can introduce complications such as delays in payment confirmation and potential issues with creditworthiness. Bank transfers can also take time to process and may involve fees or currency conversion issues if both parties are in different countries. Checks, while familiar, carry the risk of bouncing or not being cleared, causing delays and potential financial misunderstandings.

Therefore, the standard and straightforward expectation is that payments be made in cash, specifically in US dollars, to facilitate smooth and efficient shipping transactions.
