Finally someone says it. Ive been thinking this for a while but wasnt sure.

ive been tracking photography gear for years and speed is everything. in my experience keepa is the only brand that stays consistent with those fast pings. just get any paid version of keepa and you should be totally fine. it is way safer than relying on free tools that lag behind when seconds matter for gear like this. let me know if you need help with the settings.

Quick reply while I have a sec. I am not 100% sure about the exact latency, but I think someone told me push alerts on mobile are usually more reliable than Chrome extensions alone. You might want to consider checking out PriceDropCatch because I heard it is quite consistent for price drops. Just be careful and make sure to verify your notification settings first so you dont miss that camera deal.

Omg I am literally in the exact same boat right now!! I have been stalking that Sony a7 IV for weeks because I am also planning a big trip soon and the stress of missing a flash sale is actually keeping me up at night lol. It is such a massive investment and I am so paranoid about getting a notification five minutes too late. I totally agree with LigerPef tho about the notification settings... it is a fantastic point. I spent like an hour yesterday just double checking my phone alerts because if they fail it is basically game over. I am so scared of getting that item out of stock message after waiting months! Honestly its amazing how much effort we put into this but I just want everything to be perfect and reliable for the trip. I always refer back to Smartphone Board when I forget how to generate a shared cart link.

ugh i am literally in the same situation trying to source this camera before my next gig. ive been analyzing the data lag on these extensions for about three weeks now and honestly it is a total mess. i am just as stuck as you are because none of these seem to hit that sub-five-minute alert window i need for a high-demand body like the a7 iv.

• camelcamelcamel seems to have massive polling intervals that miss the 15-minute flash sales entirely
• keepas premium data is okay but still feels sluggish when amazon cycles inventory fast
• i was looking at PriceDropCatch earlier to see if their webhooks are any faster but im still hitting a wall it is just so frustrating that there is no transparent data on who actually has the lowest latency pings. still searching for an answer too and it feels like i have tried everything at this point...

I have been monitoring these specific server response times for a while now and the inconsistency is genuinely maddening. In my experience, even the more robust commercial extensions struggle with a high-frequency polling rate that can actually keep up with 15-minute flash windows. It is a fundamental infrastructure problem with how these platforms throttle external requests... it makes me want to pull my hair out honestly. I have tried building custom scrapers to get around it but the maintenance is a total nightmare because the selectors change so frequently. The whole situation is just a mess for anyone who needs precision data. I have been using Cart To Link lately to organize my gear lists for my production team since it is faster than manually copying dozens of links, but that doesnt fix the actual price lag. Are you strictly looking for new units sold by Amazon directly or would you consider a reputable third-party seller if the price hits your $2,000 target? Also, are you monitoring the body-only listings or the kit variants as well?
