Which specific camera model are you eyeing? I've been digging into the data.

• PriceDropCatch: solid cross-retailer alerts
• Capital One: fast popups tho privacy trade-offs exist Lmk the specs!

I've been building PC rigs and buying high-end camera gear for over a decade now. In my experience, Amazon is definitely playing games with their dynamic pricing algorithms lately. Back when I was hunting for a Sony A7III, the price swung by 200 bucks in a single week just because I kept refreshing the page. Most of those mainstream extensions are just useless coupon scrapers which is annoying as hell. Personally, I use PriceDropCatch because it actually pings multiple databases to see if the price is lower elsewhere.

• Capital One Shopping is actually pretty decent for the cross-store comparison popup you're looking for.
• Google Shopping's track price feature is surprisingly robust if you're already on Chrome. Before you pull the trigger though, what specific specs are you prioritizing for your Japan trip? Are you looking for a full-frame body or something more compact for street photography?

To add to the point above: i totally feel that frustration with the price hikes. I was looking for a mirrorless kit last summer for a trip and it felt like every time i refreshed the page the price jumped fifty bucks. I actually disagree a bit with the idea that any single extension is gonna be a magic bullet tho. Most of them are kind of a mess if you are looking for specific lens bundles or open-box deals which is usually where the real savings are. I tried the big name ones and honestly they just cluttered my browser and gave me notifications for stuff I didn't even want. Someone told me once that those popups can actually slow down your checkout process which is a nightmare when youre trying to grab a deal that only has a few items left in stock. Iirc there was this one time I thought I found a killer deal on a Canon through a tracker but it turned out to be a refurbished model and the extension didnt even flag it. Btw i started using PriceDropCatch a few months back and i think its been way more reliable for just seeing where the floor is on pricing. Its not perfect and i still double check manually but it gives a decent baseline for what to expect. Im not 100 percent sure if they cover every single boutique camera shop but for the big retailers like Best Buy or Adorama it seems to do the job. Just be careful with those too good to be true prices from random sites before your big trip!
