An ad-free catalogue of LEGO prices in Belarus. It sells nothing, and every price links to the shop that offers it.
Each set page shows the current price in every shop that stocks the set, and the set's own price history. A Telegram bot keeps watchlists and sends price alerts.
Most classified ads never mention the set number: 70 percent of 2,080 checked. Listings are matched by set number with exact boundaries, so 21282 never matches 212820, and by name only when the name points to one set. When it is ambiguous, the matcher does not guess. Knock-offs, used bundles, single minifigures and incomplete sets are filtered out before any price is counted.
In Belarus almost every set costs more than its US list price: 1,311 of 1,414 priced sets in August 2026. “Below list” would never fire, so the verdict compares today's price with that set's own history. A set with less than 14 days of history gets no verdict at all.
When a shop blocks the collector, the block is recorded as a block, so a blocked shop never shows up as out of stock. An unreachable shop never overwrites prices the site already holds. Bot protection is detected, and the collector stops for that run.
Everything scales to zero between runs except the database. Prices are collected twice a day. Set images were re-encoded to WebP at 1,200 pixels, which took them from 1.90 GB to 150 MB.
