Dear Sirs, RE: COUNTER-OFFER FOR MOUNTAIN BICYCLES Thank you for your letter about the offer for the captioned mountain bicycles．Although we appreciate the quality of your bicycles, their price is too high to be acceptable．Refering to the sales contract No．8998, you will find that we ordered 1000 bicycles with the same brand as per the terms and conditions stipulated in that sales contract, but the price was 15% lower than your present price．Since we placed the last order, price for raw materials has been decreased considerably．Retailing price for your bicycles here has also been reduced by 5%．Accepting your present price will mean great loss to us, let alone profit．We would like to place repeat orders with you if you could reduce your price at least by 15%．Otherwise, we have to shift to the other suppliers for our similar request. We hope you take our suggestion into serious consideration and give us your reply as soon as possible. Yours truly,
