A: During passed 9 years,we found that these buyers who paid sample fee before order have become our regular customers. Some other buyers who received free sample had negative attitude and rate of transaction was low. Some buyers who have no power to get business or have no keen purchase always reject paying courier fee. Then ,our company set a rule below so that could check resellers' power of business or user's sincerely of purchase.
Sample rule :
I)Cost of material less than 3 kg ====Absorbed by seller
II)shipping fee ====Absorbed by new buyer.
