it depends who is the non taobao freight forwarder, for me i have been using gohappytt service for 8 years; for personal and company purchase. so far so good. All his price is listed properly in excel for you to view (like a quotation) before you place order with him. i wont say he is the cheapest, but the reason i support him because of his service, its really good; besides place order, communication with seller, any mishap from seller, he will inform you, do the cancellation and refund for you. All i can say he is a trustworthy seller.

this. you provide the title, link, which option and qty, he give you a quotation and estimate weight. After make payment and provide shipping details, then he will proceed. If weight is lesser, he will refund when send out from china, if more then just top up to him to proceed the shipping. he will earn 10% of your total purchase amount (example your purchase is Rm100 after convert to RM, 10% would be RM10, total RM110 + shipping charges), which i feel its fair enough for his effort.

  item above 10kgs or bulky items he would recommend sea freight. but still it's better communicate with him to confirm.
