What does “sealed, unactivated” actually mean?

Factory seal intact — never opened, never booted. Buyers pay top dollar for these; open it and it's HK$300+ off as standard, shop depending.

How can buyback beat Apple's own price?

Early batches are supply-constrained: some buyers would rather pay over retail to have it now, so resellers buy yours and pocket the spread. Once supply normalises, the premium shrinks fast — or goes negative.

How often is this updated?

Sin Tat prices can change daily, sometimes morning vs afternoon. This page follows the latest quotes, timestamped under each table — but the safest move is still asking the shop for its live price before you commit.

Deal intel: Sin Tat iPhone buyback prices are out — 18 Pro Max flips HK$1,801 over retail!

By JengDeal editor· Last verified: 2 October 2026 (HKT)· 4 min read

Sin Tat iPhone buyback prices, refreshed daily: which of the iPhone 18 Pro Max, 18 Pro, iPhone Air and iPhone 18 actually flips for a profit — and which you'd sell at a loss — all in one table. JengDeal does the maths; always confirm the live shop quote before you commit.

Key facts

This price sheet runs from the 18 September 2026 Sin Tat reference to fresh shop quotes from the Telegram group on 2 October 2026, sealed and unactivated only. Opened or activated it? That’s HK$300 off straight away, thanks.
2 October group quotes: large blue 512GB down to HK$11,680 (WK), small blue 512GB HK$10,400 (Danna) — about HK$2,300 gone in two weeks, and a big shipment wave lands 2–9 October. Don’t catch the falling knife just yet!
This round's flip king: the iPhone 18 Pro Max! The 2TB buys back at HK$23,800 — HK$1,801 over Apple's price; the 1TB is HK$1,401 over; the 256GB HK$1,301 over. All profit.
The iPhone 18 Pro? Meh. Only the 512GB makes HK$151; the rest lose you HK$99 to HK$299. Not worth the hassle.
The iPhone Air and standard iPhone 18 are out: buyback can't catch retail, and the Air 1TB is HK$1,800 under — buying to flip is basically a donation.
Buyback prices move faster than the weather, and shops can differ by hundreds of dollars — always get the live quote before you commit, don't just trust this page.

How to use this table

“Premium” is buyback minus Apple's price. Positive = the market pays over retail for your phone, there's meat on the bone; negative = you're selling at a loss, think twice.

“Sealed, unactivated” means never opened, never booted. Open it and shops knock off HK$300+ as standard — the exact haircut is each shop's call.

“Quoted by” currently has one source, the Sin Tat reference; more shop quotes are coming so you can hunt the keenest quote.

The boring-but-important bit

Every price here is reference only, not a live quote; what the shop says on the spot is what counts — confirm it yourself before committing.

Buyback prices follow supply, FX and grey-market demand; this morning's price can be ancient history by afternoon.
