I am electronic dealer in pakistan and in first days I uae to go to china for purchasing purposes but when I get to know about alibaba I even dont need to go to china because I can directly deal with the manufacturers and see their online catalogue.
Alibaba is best and no1 wholesale dealers all in 1 place.
I reccomend alibaba to those who want to directly purchase from factory and lowest as possible prices.
You can also find delivery agents on alibaba so when you final the deal with the manufacturer your delivery agent will get the goods directly from their factory.
One big advantage of alibaba is safe payment.
Alibaba perform as a midman between buyer and seller. Once you order and pay to alibaba , alibaba will transfer your order to the seller and when you recieve your parcel and if yoi approve the order as it is in good condition according to the definition you will approve the payment and alibaba will pay to the seller.
In case your order is defected or broken you can open a dispute and provide evidence to get your payment back.
For me this is the biggest advantage of this all in 1 place website.
