Replying to [DREW23]:
We are a supplier of energy saving lamps.
We sincerely sent a lot samples to customers for free,but didn't get orders from them.That's why some supplier will ask vendor to pay the sample charges.
I'm convinced that you are not such a buyer like to ask samples from every supplier whom you contacted,whether they are good supplier or not.
It's a normal phenomena in the world. China import goods from other countries,they also charges us for samples.
So pls don't consider your own profit solely,business is basic on a mutual profit,trust, help.Most suppliers can return the charges when you place orders,i'm sure not so many country can do this .In a word,it's a great action.
