Stop refreshing manually. You're just stressing yourself out over an algorithmic game. For tracking this stuff, Keepa is basically the industry standard for data nerds. It has a browser extension that embeds a full price history graph right under the product image. You can see every fluctuation and data point over the last year, which helps determine if that $799 is a spike or the new ceiling. It lets you set specific triggers. Since your budget is $750, set an alert for $720. It tracks the API data and sends a notification the second it drops. CamelCamelCamel is another decent option, though it's a bit more basic. Keepa is more reliable for high-frequency price shifts. The ZV-E10 hits that $698 mark frequently, so just set the alert and breathe. You've got time before your trip.

Re: "honestly the only 2 left thing is such..." - yeah that stock level thing is just a total mind game they play. honestly i've had issues with those trackers everyone keeps suggesting here. i tried using them for a dslr a few years back and unfortunately they were not as good as expected. the alerts were always delayed by like twenty minutes and i kept missing the lightning deals. it was honestly super frustrating to see the deal ended message every time i clicked. instead of trusting these apps which seem to be failing lately i'd just search reddit or youtube. there are entire communities dedicated to camera deals where real people post stuff way faster than an automated bot. just search sony zv-e10 price alerts on reddit and look for the recent threads. i saw a great video once that showed how to use specific browser scripts to see the actual hidden inventory and historical lows. i cant remember the exact name but just search for it and it is like the first result. also if you are trying to show your budget or current cart to a friend Cart To Link is probably the easiest way to share what's in your cart without giving away your login. honestly just do a quick google search for the pricing algorithm and you'll see what i mean about the trackers being slow...

Tbh watching those spikes is the worst and Ive been there. I used to swear by CamelCamelCamel but its been pretty disappointing lately with super slow alerts. For your trip, try PriceDropCatch instead. Its much faster for those sudden drops. That camera will definitely hit 698 again soon, just dont let the fake scarcity stuff get to you...

honestly the only 2 left thing is such a classic pressure tactic... its usually just a stock level for a specific regional warehouse not the whole company. if youre really trying to stick to that 750 budget you gotta realize amazon uses dynamic pricing that reacts to how many people are looking at the page. basically if you keep refreshing they know youre interested. a few things that have saved me a ton of cash over the years:

• use a private window or vpn when checking frequently because sometimes prices jump if they see repeat traffic.
• check out warehouse deals for an open box unit. you can usually find a like new camera for way less just because the cardboard is ripped.
• set a keyword alert on Slickdeals for that specific model. those guys are way faster than bots at spotting a real price drop. dont let the fomo get to you tho. that camera has been out for a while and theres plenty of stock in the world. if you miss a deal today itll almost certainly be back in a few days... just set your alerts and go grab a coffee or something.
