How do you track auction lots split across multiple platforms? (launching a free tool Tuesday)

Launching here Tuesday at 12:01am PT: Auction Bid Assistant — a free tool that searches 8 auction platforms (the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector, LiveAuctionWorld, and eBay) from one search box, plus free alerts that email you the moment a saved search matches — eBay included, which I haven't found anywhere else doing.

Ahead of launch day, curious: if you buy or collect anything at auction — art, coins, watches, cards, furniture, whatever — how do you currently keep track of lots split across different platforms? Checking each site manually? Alerts from just one? Genuinely interested how people handle this today.

Follow the page and you'll get notified the second it's live Tuesday — happy to answer anything before then.
