You have an ecommerce business how can you get major product line at wholesale price like Nike Addidas etc?

Call Nike, and Adidas. Let them know you are interested in re-selling their products. They will direct you to their distributors or send you a resell packet and catalog. Sometimes you might need to buy a certain amount of products to start with them.

So to say, you cant just buy 1 pair of shoes from Nike themselves. You might be able to buy 1 pair from the distributor.

You have to call and speak with real people from the company. Be careful with middle men. Too many will leave you without any profit and a recipe for failure.
