Brickset Price Tracker

Track your own purchase/sale prices on Brickset collection pages.

Brickset tracks WHAT you own — this extension adds what you PAID and what you SOLD it for, with profit/loss against current market values. It injects a "My Prices" column into your Brickset collection pages (sets and minifigures) in all three views (List / Gallery / Table) and on individual detail pages. Track prices • Buy and sell prices per unit, with date, quantity, condition (new / used / not rated) and notes. • Mark entries as "in transit" (bought, not yet arrived) or "missing parts". • Record where you bought or sold each item and keep a link to the order or listing. • Your price is colored green or red depending on whether you paid below or above the market value shown on Brickset. Organize • Custom collections: group sets and minifigures freely, also via batch selection; an item can belong to several collections; filter by collection. • Show or hide table columns. Inventory dashboard (opens in its own tab) • All your tracked items in Table, List or Gallery view, with sorting and a search box. • Filter by collection or by sets/minifigures. • Batch actions and the same price editor as on the pages. BrickLink order import • On a BrickLink order page, each item gets a Track button. • One click imports it with condition, quantity, date, price and the order number. • Optionally spread the shipping cost across the items, or mark the order as in transit. • Shows which items from an order you have already imported. Overview & backup • Popup and dashboard show the amount invested, current market value, unrealized profit/loss, and realized profit/loss from actual sales — split by sets and minifigures. • Display currency and number format follow your browser and can be overridden. • Full JSON export and import for backup or moving between devices. Privacy: all data stays local in your browser. Nothing is sent to any server — no tracking, no external code. Market values are read only from the Brickset pages you open; order data only from BrickLink order pages you open yourself.
