Well , we've settled everything in connection with this transaction except the question of the mode of payment .   Because this order is a comparatively big one , we would like to pay by time L / C , say , 60 days L / C .   Payment by sight L / C is quite usual in international trade , and as a rule , we only accept payment by sight L / C .   But we have only moderate mean at hand . If you can do us a special favor this time and allow us to delay payment , we'd really appreciate it .
