Amendment of L/C
Dear Sirs,
We wish to acknowledge receipt of the L/C for the amount of US $4,000 covering your order No.5678 for 500 luxury fragrance lamps.
Unfortunately the amount in your L/C is insufficient, as the exact total CIF value of your order comes to US $4,300 instead of US $4,000,the difference being US $300.



In view of the above, please increase the amount of your L/C by US $300.On receipt of your amendment we shall effect shipment.For your information, there is a fast liner S.S.“Red Star”,which is due to sail for your port on June 8th. We shall shipping space on the vessel on receipt of your amendment.
Your early attention to this matter will be much appreciated.
Yours faithfully
