To opt for the new feature, tap on “Shipping Option” on the checkout page and choose Self Collection. Following that, go to “Choose Another Collection Point” and search for nearby collection points by typing in your address or postcode. Self Collection is quite convenient for those who are often away from home and don’t want to leave their packages vulnerable to theft. However, the option is only available for a limited number of sellers as of writing. According to Shopee’s customer service, the new feature is being rolled out in batches and will eventually be enabled for all sellers. (Source: Shopee [1][2])
