I only prefer DHL for costly products. Many of such items are also with free DHL charges. And many sellers negotiate for DHL delivery prices. All products which are usually below 100$, I prefer routine free offered delivery like China Mail. The worse delivery method is Seller's own delivery method which takes so long to be delivered. In local market many items are below standard because our business person usually buy cheap but we can buy through Ali Express many of best quality products like sports shoes, Jackets, Sanitary sets, Hardware like Digital locks etc.
