Jean has always paid for anything, any time in her business career using cash or 30 day terms. She understands this may have to change because orders tend to be bigger when purchasing overseas.

Bear in mind, she does NOT want to empty her bank account or have funds set aside by the bank that she cannot use. What can she do where she does not have to outlay cash or cash equivalents? (her credit card limit is $25,000)
