I will search EBay sometimes when searching for car parts, or electrical items. Often what I am looking for will not be sent to Thailand. However, after finding what I am looking for, I will often get links to Lazada or Shoppee with the same item. Their search engines are not too flash in English - but the (scary) wonder that is Google helps make the connection for me.
In Australia, I was quite happy with EBay - as a buyer, and a seller. In LOS, I have learned to live without it. The imminent changes to PayPal will be the final nail in the coffin ⚰️..
