Where to find cheap RS485 transceivers?

If you need to buy more than a few RS485 transceivers (1 receiver / 1 transmitter), you can typically find the cheapest ones on LCSC. Although LCSC charges significant shipping fees (if you don’t choose the slow mail service for shipping small quantities), the very good prices for the components themselves make it
