建议使用见票后30天应付的信用证支付

Dear Sirs,

　　We wish to place with you an order for 1 000 casks Iron Nails at your price of US $150.00 per cask CIF Lagos for shipment during July/August.

　　For this particular order we would like to pay by 30 days L/C.Involving about? US $150 000,this order is comparatively a big one.As we have only moderate means at hand,the tie-up of funds for as long as three to four months indeed presents problem to us.

　　It goes without saying that we very much appreciate the support you have extended us in the past.If you can do us a special favour this time,please send us your contract,upon receipt of which we will establish the relative L/C immediately.?　　

　　Yours faithfully，
