There is a new phenomena on Alibaba, suppliers are marking up their prices by 100-200% and they are doing that for negotiation purposes. For example, a product that was priced for 50-60$ a couple months ago is now priced for 100-200$. I think the reason why suppliers are doing this is to have more leverage negotiating with new customers, so if you end up bringing the price down to 100$ you would think you won, but in reality you paid double the original price. The suppliers I am talking about are legit factories and not trading companies, so this price-hike was done directly by a manufacturer and not a middle man. How would you approach such suppliers and make it clear that the price they're asking for is imaginary and not real at all without putting them off and possibly losing them as a business partner?
