Looks like +$102. Loses $32 after fees.
A gap between two prices is not profit. We show you the ones to walk past, too.

Why we built this
“I was done scrolling eBay for hours for one thing worth buying. A find only counts here if it still makes money after fees and shipping.”
“Anyone can spot a discount. A find goes up here only if it still pays after fees, shipping and import duty, or it does not go up at all.”
“I wanted my flips as a P&L, not a spreadsheet: buy date, sale, the profit curve. That is why the portfolio exists.”
These are ours, not customer reviews. Reviews from customers go in their own place, with their own label, as they come in — we do not write those.
Choose your plan
Same scanner, same fake check, same net after fees on every plan. The plans differ in how much you run through it.

No guaranteed profits. Data and honest verdicts — the decisions are yours.
Questions
1. What exactly does FlipSonar do?
Scan a photo, screenshot or link: we identify the product, price it against the live market, take off every fee and give you a verdict. And four times a day we search the marketplaces for you.
2. Are the prices real or estimated?
Both, and always labelled. Sneakers get the live StockX book for your size; anything read off a listing is marked “read”, anything inferred “estimated” — and an asking price is never counted as a sale.
3. Is there a profit guarantee?
No. Reselling carries risk, and anyone promising profits is misleading you. We give data and an honest verdict; the decision is yours.
4. Can the counterfeit check be wrong?
Yes. It is a risk rating from the listing — style code, price, photos, seller — not the item in hand. Authenticate anything valuable yourself before you pay.
5. What do the plans differ in?
Volume, not honesty. Every plan has the fake check and the net after fees. Starter scans your own finds and reads the board one sweep late; Pro reads it live with push and mail, ten saved searches and bulk scanning; Elite is for volume — 1,500 scans, 30 searches checked every sweep, and new features first.
6. Can I try it before paying?
Three real finds on this page open without an account (Try one), and every example above opens its full maths. Beyond that it takes a plan — cancel any time, the month you paid for runs out and nothing more is charged.
7. Is there a yearly plan?
From Oct 7, when Early Access ends: billed once a year at two months less than paying monthly. It renews yearly unless you cancel before the renewal date — we mail you 30 days before — and the first 30 days are money-back. Until then the Early Access discount is the better deal, and the two are not stacked.
8. How do I unlock full access?
Pick a plan. Whop takes the payment, your account unlocks instantly. Cancel a monthly plan any time — the current month runs out, nothing more is charged.
Stop guessing. Start spotting.
