填空题

Dear Sirs,
Hand-embroidered (手绣的) Silk Scarfs
We thank you for your offer by telex of September 3 for 5,000 pieces of the captioned goods (标题货物) at ￡ 9.50 per piece CIF Hamburg.
We immediately contacted our customers and they showed great interest in the quality and designs of your products. However they said your price is too much on the high side, i.e.10% higher than the average. They told us if you can reduce your price to ￡ 8.55 per piece, they will increase 1,000 pieces to the quantity. So there is a good chance of concluding (缔结) a bigger transaction (交易) with them if you can meet their requirement. We hope you will take advantage of this opportunity so that you will benefit from the expanding market.
We await your favorable reply with great interest.
Yours sincerely,
(Signature)
