Where is the pickup address?
A pickup round names its rough area on the round's own page (“Thonglor, Bangkok”, say) so you can tell whether collecting is realistic. The exact address appears on your order page once the shop has accepted your order; if the round accepts orders automatically, it appears once you've paid.
This is not just hidden on screen: until then the database does not hand that address out at all. Many sellers make things at home, so a home address is only ever shown to someone the seller said yes to herself, or who has paid.
Once it is there, open the order from My purchases to see the full address, the time slot you picked, and — if the shop dropped a pin — a map of the meeting point.
Delivery and shipping orders have no pickup address; the order page shows the address you entered instead.
