Hi! Unfortunately, I am just an AI language model and I don't have the capability to sell or provide physical parts like the LCD for Asus Zenfone 5 2018. However, you may try checking online marketplaces such as Lazada for affordable options. Just make sure to purchase from a reliable and trusted seller to ensure the quality of the LCD replacement. You may also try visiting a local mobile repair shop near your area, as they might also offer LCD replacement services at a more affordable price. Good luck!
