tbh manual refreshing is a total waste of time because the pricing algorithms move way faster than any human can. ive tracked optics for years and you gotta be careful with the technical lag on some of these tracking sites. if youre hunting for that sony lens, i would suggest setting up a price drop tool so you arent tethered to your desk, but there are definitely some technical pitfalls to watch out for.

• make sure to distinguish between amazon direct and third party sellers because the warranty specs on lenses vary wildly.
• check if the alert is for new or warehouse deals, as trackers often mix them up in the data feed.
• be careful with email notifications since they can lag behind the actual price change by 10 or 20 minutes. ive seen people miss out because by the time they clicked the link, the api had already updated to a higher price point. also, keep an eye on your budget thresholds. if you set the alert exactly at 600, you might forget that tax and shipping could put you over the limit anyway. i usually set my alerts about 5 percent lower just to give myself some breathing room. just be sure the tool you pick actually tracks the specific asin you need and not just a general category search or youll get buried in junk alerts.

> manual refreshing is a total waste of time To add to the point above: unfortunately, most trackers were way too glitchy... Price Drop Catch is safer for staying under that $600 budget tho.

Would love to know this too
