Most Alibaba - Aliexpress suppliers have setup the shipping charges for purchase in wholesale. http://goo.gl/w8OehW
This means when you see a product with a low price, (usually entrepeneur or individuals), try to buy one piece or a small quantity with the lower prices.
For this case, suppliers fixed a high shipping rate for avoiding one time/low quantities buyers.
This can be negotiated by contacting the supplier and explain them the small quantity purchase is because you want to test the quality.
The supplier can fix the shipping fee as per yur request.
It is recommended real time negotiation: Trade Manager / Whatsapp/Wechat/skype for better results.
Hope this helps
