You are the sales manager for US Consolidated Widgets, Inc. You get an email from a Peter Sagan with an address in Slovakia asking for a quote to sell 100,000 widgets. A sale of that size would be the biggest transaction this year. Attached to the email is set of terms and conditions. You call the telephone number in the email and have a friendly discussion about the proposed transaction. Your company has never done international business. This situation raises many important issues. What is one issue that you should be concerned about at this point?
