DealWatch: The Amazon FBA ASIN Alert Tool for Replens

July 02, 20267 min read

I made 70 euros in profit before I'd even had my coffee. I woke up, checked my phone, saw one notification, ordered 10 units, and the whole thing took two minutes. That wasn't a lucky one off. That's what happens when you've got the right amazon FBA ASIN alert tool running in the background while you sleep.

DealWatch is a tool inside ProfitPath, an Amazon FBA sourcing software suite, that watches your own list of ASINs and pings you the moment one becomes profitable based on your numbers. We can currently scan up to 48,000 ASINs and we run around 37,000 active right now.

What DealWatch Actually Does

Most sellers source the same way. You sit down, open the tools, start checking products one by one. The moment you stop, the sourcing stops too. That's not a system, that's a job you've given yourself on top of your actual job.

DealWatch flips that. You give it the products you actually care about, your own ASIN history, the things you've sold before or know sell well, and it watches them constantly. The moment one of those ASINs becomes available at a price that meets your margin and profit targets, it pings you. On your phone, on your computer, day or night.

I've been selling on Amazon for over 10 years now. We've done almost 10 million euros in sales across the UK and Europe, and DealWatch is one of the reasons last month alone we found over 700 profitable products through ProfitPath.

A2A vs DealWatch: What's the Difference

If you watched the last episode in this series, you already know how A2A works inside ProfitPath. You set your buy and sell regions and your margin targets, and it builds you a private alert system based on those parameters.

DealWatch takes that further. It's not just watching for any product that matches your criteria, it's watching specific ASINs. Your products. The ones you've already proven sell. A2A casts a wider net across the marketplace. DealWatch goes deep on the exact products you tell it to track.

That's the core idea: A2A finds new opportunities, DealWatch finds more of what already works for you.

Why Your Old ASINs Matter

Here's something most sellers don't think about. Pull your entire sales history, every ASIN you've ever sold, profitable or not, and add the whole list into DealWatch.

Why the unprofitable ones too? Because DealWatch only pings you when a product is actually profitable right now. You might have sold something at a loss six months ago. The Amazon price may have gone up since then, or you might be able to source it cheaper today. These are replens, and they're some of the easiest wins in this business because you've already done the hard part. You know the product sells.

Setting Up DealWatch: ASINs, Alert Types and Filters

The global settings carry over from the rest of ProfitPath, so if you've already set up your marketplaces, blacklist and other parameters, you don't need to redo any of that here.

To create a new alert, you add your ASINs. You can drag and drop a file or paste them in manually. If you don't have a list ready yet, ProfitPath gives you a starter pack of ASINs so you can get going straight away and swap them out later.

Once your ASINs are in, you choose your alert type. A2A, store alerts, or both. Then you name your group, enable Discord notifications, and create it. From that point, the system is running for you around the clock.

You can also set your minimum margin, ROI, profit and minimum sales right here. So you're not only watching specific ASINs, you're also filtering for the numbers that actually matter to your business. Set your own parameters. What works for me won't be exactly what works for you, and that's the point.

A Live Deal: €236 Spent, ~€730 Expected Back

So let's get into real numbers, because that's what actually matters.

Yesterday morning I bought a product for 23.53 euros per unit. I ordered 10 units, total spend of 236.06 euros, with an expected profit of around 73 euros per unit, roughly 730 euros back. I bought it in Italy and we're selling it in Germany and the UK. The whole thing took two minutes on my phone, before breakfast.

Does that happen every single morning? No. But it happens more often than you'd think, because the system is always running, even when I'm not at my desk.

Every alert that comes through has already been filtered against your margin, profit and sales targets before you ever see it.

How the Discord Alerts Work in Practice

When an alert fires, it lands straight in your own private Discord server. Not a shared lead group with hundreds of other sellers seeing the same ping. Your server, your alerts, your deals.

When I get a notification, I open it, check the product is still available, confirm the sales history, glance at the charts, and if I'm happy, I buy it straight from my phone. No laptop needed. I keep all five of my marketplaces, UK, France, Italy, Germany and Spain, logged in on separate browsers so I can move the second a deal fires.

One example that came through during this video: a product available in Spain for 8.93 euros, selling in the UK for around 23 euros, with roughly 6.44 in profit and about 50 sales a month in the UK. No variations to worry about. That's the kind of opportunity DealWatch surfaces while you're doing something else entirely.

If you've never set up a Discord server before, don't worry, it takes about two minutes. Create one for you and your team, head into integrations, add ProfitPath, and every alert from this point lands straight there.

Frequently Asked Questions

What is an ASIN alert tool for Amazon FBA?

An ASIN alert tool monitors specific products you choose and notifies you the moment they meet your buying criteria. Instead of manually checking the same products every day, the tool does the watching and only flags a product when it's actually worth buying based on your own margin and profit targets.

How do you find replens on Amazon FBA?

The best place to start is your own sales history. Pull every ASIN you've ever sold, profitable or not, and feed that list into a tool like DealWatch. A product that wasn't profitable months ago might be profitable today if the Amazon price has moved or you've found a cheaper supplier.

How do Amazon price drop alerts work for sellers?

Most price drop alerts simply tell you when a price falls, regardless of whether that's actually a good deal for you. DealWatch goes a step further by only alerting you when a product hits your specific margin, profit and sales targets, not just any price movement.

Can you automate Amazon FBA product sourcing?

Yes, to a large extent. Tools like A2A and DealWatch inside ProfitPath continuously scan for opportunities based on parameters you set once. You still make the final buying decision, but the searching and filtering runs in the background around the clock.

Is ASIN tracking worth it for Amazon sellers?

If you've been selling for a while and have a list of products you know perform, tracking those exact ASINs is one of the highest hit-rate ways to source. You've already proven the product sells. You're just waiting for the price and margin to line up again. For more on building your own alert system from scratch, check out the A2A arbitrage episode earlier in this series.

What is the difference between DealWatch and a lead group?

A lead group shares the same deal with everyone in it, often hundreds of sellers, so by the time you see it the listing may already be filling up. DealWatch only searches the ASINs and parameters you set, privately, so the deals it finds are not shared with anyone else.
