How to keep track of amazon.in prices? Is there something like camelizer?

Edit: This seems ok https://pricehistoryapp.com/

Trying to get a decent price tracker on Android and honestly most of the stuff on Play Store feels lazy. Half of them are just apps that forward deals from some Telegram group instead of actually tracking anything.

I just want something simple that can track my items, send me a notification if the price drops or if there’s a coupon. Would be great if it works across different Amazon regions too since I order from more than one site sometimes.

Everything I’ve tried so far looks outdated or half-broken. Anyone here actually using one that still works in 2025?

I built this gaming products price trend / drops tracker for Amazon IN buyers. Take a look, and give me some feedback. I am lacking positive motivation to build more. It has ZERO visitors...

Tech Stack:

• It's frontend is built on Astro+Svelte. Backend is Supabase.

• Supabase is fed with daily prices using a FastAPI cron job from Github Actions.

• To scrape amazon, I use AmzPy pypi lib.

so ive noticed lately that after i buy an item it winds up being a cheaper price within my return window option so ive started repurchasing the same item a 2nd time at a lower price and then sending it back with the original order where i paid a higher price.

my understanding is amazon hasnt done price adjustments in several years and even though its more inefficient thats what they prefer you do.

these price differenced will range from $5-10/item but it adds up quickly for our family when we order so many things we need. i regret to think how much extra $ has been spent on purchases over the years from price swings.

in the past few weeks alone im recouping about $50 in price difference.

the trouble is im manually checking the prices for fluctuations daily because you never know when they will go up or down.

ive observed the algorithm will lower the price the more you view an item to entice you to buy because it believes youre really interested and just need some motivations.

ive also noticed prices go up for an item after youve completed just a regular return. im sure the merchant or algorithm is trying to pass the cost of the return off to the next customer there.

anyway, the apps i see on the play store (im on android) seem outdated and not sure if i can trust them.

is there an updated app that works well to notify you of price swings or coupons available on the items you wish to track? ideally it would be nice to sync to your amazon account so it adds the items for notifications automatically. if not an app then a good browser extension for chrome?

some credit cards used to have a price rewind that was great for this purpose but they've all but discontinued that feature across all credit card issuers.
