Replying to [QUESTIONS]:
According to your questions, it seemed you r an exporter, I presume. There may be some guys request for sample as free whether they bare the courier charges or not. But look at their side, they may asked several suppliers and logically they cannot bare the expenditures for all. And then again I am sure they may dare to order at once without testing the sample from newly contact.
If you are importer will you do it like that?
On the other side, for the sellers ofcourse they don't wanna waste the money for no good resons. But I think any seller can sense how serious the buyer is. Am I right? Seller can take precaution in this matter no matter what.
In Ms Rachna case, that's some kind ill treatment from western people. What they know is just squeez them out. If I say so I'll be one sided. as I see many trader have been damage the reputaion by themselves. So my opinion is be transparent and be honest, the time will talk.
The buyer or the seller, who ever you are, if you serve the best, they will come back later.
No sweat Question! Cheers
