Replying to [DREW23]:Hi,friend,this is very normal not only in China,I think it is popular in all business.For the first time cooperation,both buyer and supplier need honest and reducing risk.For supplier,they maybe supply many samples to different customer everyday,so if all is free,it is also a big amount of cost for them.And you know,NOT each sample can bring a order,most of them are respond by nothing.
So now it is very common like this: ask some charge of samples,even more than value of goods to avoid the sample cheater,then refund the fee to buyer when they bring a real order in the future.
This is fair for both side,just understand each other,remember: Good beginning is a half of success.
