Dear Sir,
We saw from your advertisement in the Bangkok Post of 4 May, 20XX that you are an agent for printers.
We would like to buy 8 printers for our new office in Phuket. We would therefore like to have a catalogue and a price-list of your whole range of products. Moreover, we would like to know your terms of payment, including what kind of discount is available on the 8 printers we would like to order. Please send all details to me at the above address.
We would greatly appreciate your prompt reply, as we need the printers urgently.
Yours faithfully,
Teddy Sinberg
Manager
