The Rude Arrogance of a Sales Manager

As is often with our projects, we recently started negotiations for procuring 7" laptops for a client's proposed campaign give-aways. We contacted several manufacturers and/or trading companies. As part of our further inquiry to a specific manufacturer, we asked "What is the lowest price for your PC701 LX with Wifi? Our target price is under USD100 FOB. Current negotiations with potential suppliers range from USD80 - USD97. While price is a primary consideration, we also factor in reliability and after-sales support."

Imagine our surprise and shock when we received this response (printed verbatim):

Dear Sir,

In case you are ignorant, there are only 2 manufacturers producing 7" laptops. We are one of the two and our only competitor is offering it at USD10 more expensive. All the rest suppliers are our middle agents or trading companies. If you think you can buy PC701-LX with WiFi at the price range you mentioned, try to do business with them and good luck. We have time cost and please contact us only if you seriously want to do business with quality manufacturer.

Yours sincerely,
Eric So
Sales Manager
Exon International Technology Co Ltd

Considering this is a reply for a pre-sales inquiry, we have to wonder how they treat clients with quality or tech support problems. And the guy is supposed to be the Sales Manager of a company that claims to be a major player. And quite frankly, we contacted them because they are supposed to be price competitive, not because they are known for quality. Boy oh boy.
