It is a Business e-mail, please help me?

Where is your letter??

it is here....sorry:

Your prices are getting better, but we are not prepared to import anything in the next months, due to the present market situation

Or better:

Your prices are getting better, but unfortunately we do not have a perspective for any new importation in the next months, due to the present market situation.

You are not using the word "perspective" correctly.

Simply say "I regret that the current market conditions preclude any new orders over the next few months."

Why do you need to mention that their prices are getting better? You're not going to order from them anyway.

I need to mention that their prices are getting better because I have asked a better price and they gived me a percet off, but anyway I can not to import because the market crisis.

This sentece prices are getting better is correct? ( I want to tell the price is smaller. I am a buyer, because is better)

I appreciate the efforts you have made to offer us a lower price. Unfortunately, the worsening economy will preclude any further orders at all for the next few months. I look forward to doing business with you again when the situation improves.

-- I assume you're simply telling them you're not ordering. You're not looking for them to lower the price even further?

Yes it is what I want to mean

Thank you very much!!
