LINE Shopping and seller chats inside LINE are a normal way to buy in Thailand. The checkout is built for a Thai address and, often, PromptPay or a Thai bank transfer. It does not ship to a foreign address.
When a mailbox works
Use a Thai address when you can pay the seller yourself and they will deliver to a street address with your suite code. That is the same path as Shopee Thailand and Lazada Thailand.
When Buy For Me is the path
Most LINE sellers will not take a foreign card. Send the product link or a chat screenshot, the price, and how the seller will release the goods to our Thai address. Buy For Me purchases that listing. We do not pick a LINE shop for you.
Finding a seller, or negotiating a price you have not already chosen, is procurement, from THB 10,000 (approx $300) per order.
After it arrives
We photograph intake at Hua Hin or Bangkok, then you forward on the shipping calculator. The number on that screen is the freight price.
Restricted goods still follow what you cannot ship.
