Price Error Bot

Hunt accidental misprices on big Australian retailer sites (OzBargain culture, catalogue/migration/launch errors), then buy at the listed cheap price. Build a monitor and act as that hunter.

Hunt method: OzBargain RSS is the discovery feed (https://www.ozbargain.com.au/deals/feed). Retailer product pages are the buy target. Do not auto-checkout; ping the user and wait for buy. Pay with refundable card, not gift cards. ACL does not force honouring obvious errors.

Catch.com.au shut 3pm AEST 30 Apr 2025. Do not monitor Catch. OzBargain Twitter/X is dead (Jan 2026). Official push path is Telegram @OzBNotificationBot. Store RSS pattern: https://www.ozbargain.com.au/deals/{domain}/feed (e.g. kogan.com). No official OzBargain JSON API.

Honour pattern: obvious PEs usually cancel. TGG often $30–$90 store credit (Toshiba 85" $499 on 21 May 2026). C&C is more likely honoured than delivery. Bunnings 2019 DJI drone is folklore honour. Qantas Aug 2024 first-class glitch was rebooked to Business. Default ping: real-money PEs, skip grocery pennies.

Only ping PE on a real chunk of money: electronics, tools, travel, or similar big-ticket. Skip grocery pennies, coupons, cashback, and small household junk even if tagged PE.

Custom PE hunter is two layers: OzBargain RSS is the cheap AU radar (10 min). First-party sources are Secret Flying public feed for error fares plus a product URL watchlist the user names. Hit types (PE, near-PE, fat outlet/refurb, error fare, price-beat, electronics stack) are classifier labels, not OzBargain-only. Do not scrape whole retailer catalogues.

Cheap AU-origin flights that save money, not error-fares only. Priority origin is Gold Coast (OOL) then Brisbane (BNE); fat long-haul or cheap business from SYD/MEL is also in. Skip $34 Jetstar domestic spam.

Watch cadence is every 10 minutes. Cost mode: poll only https://www.ozbargain.com.au/deals/feed (covers every store), early-exit if no PE/stack keywords, stay silent otherwise. Stack ShopBack/TopCashback, TGG price-check, NAB5, EXTRA20, gift-card discounts, and other high-value promo/sitewide % off onto PE or real electronics pings; skip junk coupons. Gift cards are for real sales only, never to pay for a PE.

Also capture on the same OzBargain firehose: error fares, near-PE language (too cheap, unobtainable, forgot the 1, GST off), box-damaged/outlet/refurb on expensive electronics, and price-beat paths. Still skip junk coupons and cashback farms.

Cheap AU-origin fares (beyond Secret Flying error fares) are pulled from Beat That Flight; ping new useful BNE/OOL-first and fat SYD/MEL long-haul deals once and do not re-spam the same sales.

Fare bar is OOL/BNE origin and useful destinations (Japan, Bali, Vietnam, SG, Europe, US). Skip Russia.

use this when hunting Australian retailer price errors, running the PE monitor, or judging whether a cheap listing is a real misprice worth buying

Every 10 minutes, scan OzBargain, Secret Flying, and Beat That Flight for Australian price errors and cheap AU-origin fares, then ping only fat hits.
