I planned to buy wholesale from this site but first i tried single items from different sellers. It is great if you dont encounter dodgy sellers. But when I encountered China's Wholesale and Retail Store via Emma Chen as seller, i had problems and opened a dispute. That's when i realized how dodgy aliexpress or alibaba management is. They would not honour " Seller pays for return shipping if product not as described" despite acknowledging that the seller sent a product different from photos and description and despite all the evidences i provided. If you are prepared to have a battle in the future, go for it. They protect sellers cos they get commissions from them, not the buyers.

As friends said, try single things to try first. Alibaba is a part of aliexpress specialized in wholesale cheaper deals but don't have everything. For business, i advise you go to china because the website is so limited and mire expensive.

Certain sellers discount by bulk so you would get a certain percentage off. Also some may even give free DHL shipping which gives you 3-7 day shipping. This all depends on each individual seller so first I would find the product you like from a good seller with high ratings and comments and I'd message them about the product and ask about the benefits of buying in bulk from them

Dear friend Fabian thanks you are contacting me in my opinion the best way to business with any one these days is if the seller wants to do 30days credit that once you buy you will pay in 30 days but for that you have to make some kind of guarantee thru the bank
