Copperline
An auction house helper built for Hardcore (and Classic Era): price scans, one-click posting, deals, a full ledger and profit stats, in one window.
Type /cl to open it. Copperline scans the auction house, keeps a price history for every item it sees, and uses it to tell you what to post, what to buy, what to vendor and what to disenchant. No libraries and no other addon needed. If TradeSkillMaster is installed, its market value can be used too (Settings).
Features
- Scanning: full and item scans, automatic scans, a market value per item worked out the way the big auction addons do (cheapest listings, outliers dropped), and a 2 week price profile.
- Sell: a verdict for every item in your bags (sell, hold, vendor, disenchant), suggested price and stack, live queue and totals, and Post next to post one stack per click. Uses the game's real deposit and 5% cut.
- My Auctions: what sold, what is undercut, and Cancel next undercut (bind it to a key to clear them fast).
- Deals: every priced item checked in the background for flips, vendor exits and disenchant value, with filters for sell rate, budget, minimum profit and confidence. Nothing is hidden, only marked.
- Search: find any item by name, level, class, rarity and usable, with prices, return, profit and sell rate. An All listings view and a vendor flips filter.
- Professions: crafting profit, the cheapest leveling path between two skills with a shopping list, and the leveling materials for nine professions.
- Ledger and Home: every sale, purchase, mail and loot, gold by source, net worth across your characters, and how fast your items sell.
- Panels beside the bank, mailbox, vendor and disenchant: put away or take out items by sell verdict, sell gray items, mail items and gold to your other characters, disenchant one item per click.
- Made for Hardcore: it knows self-found characters (no auction plans, deal advice or mail sends for them; you can override the detection in Settings), and it keeps the gold you need for essentials out of deal buying.
- Mistake check:
/cl checkchecks every deal's numbers and prints anything that looks wrong.
