Alibaba is a great tool! I loved it since the very first time I started using it. I got three diferent sample orders and am very satisfied.
A couple of things that could be improved are: One, include a more complete comercial invoice. In order to import, information such as HS code is important to know and should be included within the invoice. Two, providng an invoice for the transaction fee wouldnt hurt you.
Thanks Alibaba. Keep doing things great!
