For your first flips — side income, sourced at yard sales, without the gut-churn

What should you pay? Know your max before you haggle.

Found something at the yard sale, the flea market, or the trade-in counter — and the seller’s already named a price? Snap a photo, tell Sourcing Radar what they’re asking, and it calls it: buy or pass — with your Maximum Buy Price to back the counter: the most you can pay and still keep a real profit after fees and shipping, worked out from the real eBay sold comps you provide. A price list tells you what things sold for — your max tells you what to do. One deal where you lose money can cost more than a whole month of lookups — know before you pay, and don’t get stuck with the lesson.

  • 01 / yard sales & flea markets

    Yard sales & flea markets

    Found your first thrift-store score — a bin of camera lenses, a wall of jackets? Snap one photo, tell it the bin’s asking price, and know what you should pay before you counter. Anyone can look up a price — the verdict is the part beginners get stuck on; almost nobody can set a max under pressure. Don’t overpay for the lesson.

  • 02 / trade-in counters

    Trade-in counters & pawn shops

    The counter names a price and you’re not sure it’s fair. Your max comes with a suggested opening offer — so you know where to start before you nod, instead of getting stuck with a bag of regret on the drive home.

  • 03 / lots & pallets

    Lots, pallets & bulk buys

    Before you buy the pallet, enter what the seller wants and get your max for the lot — know what each piece can really make before it’s in your trunk, not after it’s stuck in your closet.

how your max gets made

the eBay sold comps you provide + your fees and your shipping in — a real profit target out: that’s your Maximum Buy Price

How it works

From photo to a price you can defend in three steps

  1. 01

    Snap the item

    Standing at the yard sale, flea market, or trade-in counter: take a photo, or paste a link if the item is already online. No account, nothing to install.

  2. 02

    Add the asking price and the sold comps

    Type in what the seller is asking, and add the eBay sold comps for the item — the ninety days of completed sales you gather on eBay: median, typical range, direction, in one place. That’s the raw evidence your max gets built on.

  3. 03

    Get your Maximum Buy Price and the verdict

    Your fees and shipping come out, and the math lands in plain numbers before you hand over the money: your max — the most you can pay and still clear your profit — a suggested opening offer, and the buy-or-pass verdict to back it — you know before you pay. A price list tells you what things sold for — the max tells you what to do. It’s quick because the data is ready, so the item never leaves your hand as a mistake.

What’s included

Prices move — your max goes stale without a refresh

Sourcing Radar is a monthly data subscription — it keeps working after the first lookup, because the comps behind every Maximum Buy Price move, and yesterday’s max is this month’s overpay.

FAQ

Straight answers

Where does the data come from?

From real sold and completed listings on eBay, delivered through eBay’s official API — the same records any buyer can pull up on eBay itself. You bring the real eBay sold prices for the item you’re standing in front of; Sourcing Radar does the fee math and turns them into a Maximum Buy Price. No private data, nothing you can’t already see on eBay today.

Only eBay?

For now, yes — on purpose. The beta goes deep on one marketplace instead of spreading thin: real eBay sold comps, fee math, and a Maximum Buy Price that’s ready while you’re still standing there. More marketplaces are planned — we won’t promise a date until it earns it.

Why not just use eBay’s built-in research tools?

They tell you what things sold for — a look back at what already happened. Sourcing Radar tells you what you should pay — forward-looking, for the moment you’re actually negotiating. The desk session and the counter are a different moment: standing at the yard sale, unsure whether the asking price is fair, with no time to dig. One snap, and the sold comps turn into your max, a suggested opening offer, and a buy-or-pass verdict to back it — so you know before you counter, not after.

I’ve never flipped anything. Is this for beginners?

That’s exactly who it’s for. You don’t need to know what anything is worth — the sold comps, the fees, and the profit math are laid out for you, and the answer is a plain max price and a buy-or-pass call. No experienced eye required; the same records pros browse by hand are turned into one number you can defend.

Do you need my eBay account or my sales data?

No. Sourcing Radar reads public listing data only. There is no account connection, and your inventory or sales are never uploaded. If you join the free beta, your email is the only thing we keep.

What happens after the beta?

The beta is free while it runs. When it ends, Sourcing Radar moves to $9.99/month — but founding members keep $4.99/month for life, locked at the rate they joined. The beta itself stays free end to end; no card is asked for and nothing to cancel.
