To add to the point above: I have this exact same issue... been struggling for months. Unfortunately PriceDropCatch hasnt been as good as I expected for these pedals. It is super annoying.

I was super satisfied when this eBay price tracker finally pinged me about a price drop on a rare BOSS. It automates everything perfectly and kept my gear budget safe so I dont overspend.

Just saw this and totally get the struggle with the Boss pedal hunt. Ebays native tools are basically useless for price tracking because they only care about volume, not the lifecycle of a specific listing. Building a custom scraper is usually a nightmare since eBay has some pretty heavy anti-bot protections that change constantly. You would spend more time fixing the broken code than actually hunting gear. I have been quite satisfied using a dedicated monitor instead. Setting up PriceDropCatch for my gear searches works well for exactly what you are describing. Basically, these tools ping the eBay API or use cloud-based renders to check the specific listing ID at set intervals. When the seller finally gets desperate and knocks that 480 price down to your 400 target, you get a notification instantly. Its way more reliable than trying to refresh a browser tab and hoping for the best. If you dont want to go the automated route, the only real alternative is checking for the Best Offer button. If they have that, you could just send your 400 bid now. But for a vintage Boss pedal where collectors are vultures, you usually want that automated ping the second they drop the actual list price. My experience has been positive with how it handled my last few rare finds without having to babysit the app. No complaints so far, it basically sits in the background and does the heavy lifting while I am busy.
