Don't buy the same model that is too different from other merchants. The price difference within 100 is acceptable.
Don't buy products with complete colors and sizes and large inventory, because Adi is a futures, and there is no replenishment. Generally, a product will not buy too much.
Don't buy a store with too few SKUs. Merchants selling fake goods generally don't have too many products. If 2300 of them are classic models, they are basically fakes.
