To offering similar products is easy for starting the business, and you can even lower some price to make it even easier. But it's truth, the similar products make the buyers resell hard. The profit only appears when the buyer sell the orders to their clients, it's nearly nothing about the original cost importing from China, as evrybody know that the original cost of China supplier is nearly same. Differentiation We Need, go to make the taste, the material, the colour, the texture, even the packing different. If possible, offering exclusive collection to ddifferent buyer(we are doing so), is even better, because the buyers sell different products(our pproduts are paintings) to differnt clients, and then we will give more feedback back to you and push you making new collections which more and more differentiation will be.
