How to Buy Secondhand Safely on SOI.market
Updated 2026-06-15
A complete guide for secondhand buyers: how to vet a seller, choose a safe payment method, meet up with confidence, and recognize common scam patterns before you pay.
Read the listing closely and check the seller's profile first
Before you commit to a listing, read the full description, look closely at the actual photos of the item, and check where the seller placed it on the condition scale — new, like new, good, fair, or for parts. If the only photos look like stock images or none show close-ups of wear, ask for more before you decide anything.
Then open the seller's profile. Look at their verification badges (phone verified, ID verified, address verified), review score, and how many items they've sold. A fully verified account with a sales history is usually easier to hold accountable if something goes wrong — but verification is a signal, not a guarantee. Use it as one input, not the whole decision.
Choose how you'll pay: escrow-protected SOI Pay, or cash at the meetup
For listings that support SOI Pay, your payment is captured and held by the platform the moment you check out. The seller isn't paid until you confirm you've received the item, or until a 72-hour auto-release window passes after delivery. If something's wrong, you can open a dispute before that release happens, which freezes the payout until it's resolved. This is the safer path for shipped items or higher-value purchases where you want a clear paper trail.
If you agree to meet up and pay cash or transfer on the spot, there's no escrow behind that payment — once it's sent, it's sent. Inspect the item thoroughly before handing over money. Never send a deposit to a stranger through a personal bank transfer outside the app, no matter how the request is framed.
Meet up safely
Pick a busy, well-lit public location — a BTS/MRT station, a mall, a coffee shop — somewhere with people around and ideally cameras. Avoid private homes or isolated spots, especially for a first transaction with that seller. Meet during daylight, and if you can, bring someone with you or at least tell someone where you're going and who you're meeting.
If anything feels off when you arrive — a last-minute change of location, someone different than who you were chatting with, or just a bad feeling — you're always allowed to walk away. No item is worth your personal safety.
Inspect the item before you pay, every time
For electronics, power the item on and test it in front of the seller — screen, speakers, camera, charging port, and battery. Don't take "tested, works fine" at face value without checking yourself. For higher-value items like branded bags or watches, compare the exact wear marks, stitching, and included accessories against the listing photos.
If you're paying by bank transfer at the meetup, wait to confirm the money has actually landed in the account before handing over the item — don't release the item the moment you see a bank app screenshot, since those are easy to fake.
Recognize common scam patterns
Watch for these red flags: pressure to decide fast because "someone else is about to buy it," requests for a deposit before you've seen the item or had a real conversation, refusal to video call or meet somewhere public, a price far below what similar items go for, or a seller who keeps finding reasons to steer you away from SOI Pay checkout toward a personal bank transfer instead.
Another common pattern (if you're the seller) is a buyer sending a fake transfer slip, or "accidentally" overpaying and urgently asking for the difference back before the bank confirms the real transaction never happened. If you see any of this, stop the transaction and consider reporting the user in-app.
Frequently asked questions
How safe is money I pay through SOI Pay?
Your payment is held by the platform from the moment you check out. It's only released to the seller after you confirm receipt, or automatically after a 72-hour window once delivery is marked complete. If you open a dispute before that window closes, the payout to the seller is frozen until the dispute is resolved.
What if the item I received doesn't match the listing?
If you paid through SOI Pay, open a dispute in-app before confirming receipt or before the 72-hour window closes — this freezes the payout to the seller. Describe the issue and attach photos. If you paid cash at an in-person meetup outside escrow, that transaction has no built-in protection, which is exactly why a thorough inspection at handover matters so much.
What do the different seller verification badges actually mean?
There are three independent badges: phone verified (confirms they're reachable), ID verified (Thai national ID checked against a live face scan), and address verified (proof-of-address document checked). A seller might have one, two, or all three. More verification generally means it's easier to hold them accountable if something goes wrong — but it isn't a guarantee every transaction will be problem-free. Weigh it alongside their reviews and sales history.
Should I send a deposit before seeing the item in person?
No — avoid sending a personal deposit to an unfamiliar seller to "hold" an item, whatever reason is given. If you want to secure a high-demand item with real protection, use SOI Pay checkout instead: the funds are held by the platform with a verification step before the seller is paid, unlike a direct transfer, which leaves your hands with no protection at all.
