EST. 1828 · THE PRICE-INTELLIGENCE HOUSE

Know the real price
before you buy.

The pre-owned market for the great houses is vast, fast and quietly irrational — the same bag, the same condition, swinging thousands across marketplaces in a single week. We watch it, and signal the moment an authenticated listing falls genuinely beneath its comparables.

01 — THE INVITATION

Set your ceiling.
We will watch the rest.

One bag, one number. When an authenticated listing crosses beneath your ceiling and beneath its comparables, you hear from us first — before it reaches the feed.

The method

THREE MOVEMENTS · NOTHING MORE

Choose the grail

Model, size, leather, hardware. Precision matters — a Togo 25 and an Epsom 25 are not the same instrument.

Set your ceiling

One all-in number — duty, shipping and tax folded in. We never quote you a price you cannot actually pay.

Receive the signal

A single dated note the moment a verified listing sits meaningfully below its comparable median. Then silence again.

COMPARABLE RANGE $21.4k–$26.9k Rolling 90-day window, like-for-like spec only.

LISTING AGE Flagged Stale inventory is priced differently. We say which is which.

AUTHENTICATION Verified first We prioritise listings covered by marketplace authentication.

ALL-IN PRICE Landed cost Item, shipping and estimated duty & tax, where they apply.

HOUSE RULES

What we will
never do.

I. Independent

We earn a referral fee when you buy through a link — never a commission from a seller. It never changes which listing we signal.

II. Sourced & dated

Every figure carries its origin and its timestamp. If we cannot cite it, we do not print it.

III. Authenticated first

During beta we prioritise listings covered by third-party authentication. Doubt is disqualifying.

IV. Not investment advice

We price handbags, not futures. Buy what you will carry, at a number you can defend.

IN THE HAND

The signal travels.

Signals arrive as a single quiet card — the chart, the delta, the all-in figure and the direct link. Read it in eight seconds, decide in ten.
