Frequently Asked Questions (FAQ)

Everything you need to know to sell smoothly and with complete confidence.

Why is this service 100% free for life?
Postdii aims to cultivate a thriving local secondhand marketplace. We believe sellers should keep their hard-earned cash, so we charge 0% commission. We earn revenue purely from optional features, like premium featured points to boost items to the front page.
How does the AI post assistant work?
When creating a listing, upload your product images. The built-in AI will analyze the images, generate structured descriptions, pick the appropriate category, and suggest competitive prices. It saves you from manual typing, reducing listing time from 5 minutes to just 10 seconds.
Is chatting directly on LINE safe?
Yes! The marketplace links your contact button to your personal LINE link. Buyers can reach you instantly inside LINE so you don't have to keep refreshing our website to check messages. You can also view a buyer's verification status and rating history on our platform before selling.
How does the Escrow middleman system work?
With Escrow, the buyer pays securely into Postdii's safe holding account first. We notify the seller that funds are secured and that they can safely ship. Once the buyer receives and confirms the item is in good condition, we immediately transfer the funds into the seller's digital wallet. 100% fraud-proof!
