Your price is very high and i can get lower price from other supplier.

First, You can always get some lower price from some suppliers in China. There is no lowest price in China at all. There is only much lower price one by one.

    Of course, if you could bear various kinds of bad problems and invalid commitment of cheaper productions. Their price is cheaper $ 1 than us and you can earn 10000 USD on 10000 pcs parts. But you will lose more than 10000 USD, even more lose a faithful customer if it happened a mechanical mishap occur. At the same time, I don't think you can get more  higher efficiency of the supply when you get a price which is lower 0.5-1 USD because  price elasticity depends on different service.

    Finally, you are an expert in the filed, if they can give you an offer which is even lower than the cost. What will you think about it.

    What you will get is what you paid for.

You can call me if you have any questions ,we will reply you as soon as possible!
