I place an order 2.80 a pair, before supplier confirms the order she said raised the shipping thats not fair. The Allways Change the Pricing. That not fair

In the past, just a few years ago the seller were afraid to post there personal photos or personal details like phone numbers etc. That all is the Past!
Most companies have facebook pages! Sometimes even the seller has one of it's own attached to their company! They like to connect on whatsapp or wechat.
You can verify all companies on Alibaba, and if you are smart enough you can even see the location of the company on google maps!
GET TO KNOW THE PLATFORM AND THE SELLER!
Be Polite and you get yourself the best Serving Seller!
