Why I Built Deal Scout 360: A Developer Who Flips on eBay

Hi, I'm Joe. I'm a software developer by trade and an eBay reseller on the side. I built Deal Scout 360 originally as a personal tool to find resell inventory faster. It worked so well that I decided other resellers needed access to it too.

The Problem I Was Solving for Myself

I flip items on eBay — mostly electronics, sports cards, and collectibles. The best deals disappear fast. By the time I manually found an underpriced listing, someone else had already bought it.

eBay's built-in alerts didn't work for serious flipping. They filter by item price only, not total cost with shipping. A "$15" alert would end up being $24 shipped — breaking my margin. I'd waste time clicking listings I couldn't actually buy.

I needed a tool that would monitor eBay 24/7, calculate the real total price including shipping, and only alert me when a deal actually fit my budget. So I built it.

What I Built

I'm a developer, so I built a background monitoring system that runs continuously:

• Monitors eBay for my target keywords around the clock
• Calculates total price (item + shipping) for every listing
• Skips "calculated shipping" listings where the real price is unknown
• Sends me an instant email only when a deal fits my actual budget
• Supports OR-logic so I can monitor multiple keywords in one search
• Filters auctions by end time so I can snipe deals ending soon

I ran this locally for myself for about six months. My monthly flip volume went from 12-15 items to 30+ items because I was catching deals I would have completely missed otherwise.

Why I'm Making It Public

Every reseller I talked to had the same problem: missing deals, wasting time on listings that shipped too expensive, manually refreshing eBay searches hoping to catch something.

I realized this wasn't just useful for me. It solved a real gap in the market. So I rebuilt it as a proper SaaS product that other resellers could use.

The free tier gives you three saved searches with full shipping-aware monitoring. That's enough for most casual flippers. If you need more searches or faster scan intervals, paid plans are available. And for this launch, there's a lifetime deal at $99 — one payment, no monthly fees, Pro features forever.

What Makes It Different

As someone who actually uses this tool every day to find flips, here's what matters most:

Shipping-aware price filtering. When I set a $30 max, that's my all-in budget. I only get alerts for deals where item + shipping = $30 or less. No surprises at checkout. This alone makes it worth using.

OR-logic keywords. Instead of three separate searches for "Jordan 1", "Jordan 4", and "Dunk Low", I run one search: "Jordan 1 OR Jordan 4 OR Dunk Low". Cleaner, faster, easier to manage.

Auction end-time filtering. I can set it to only alert me for auctions ending in the next 2-4 hours. Perfect for sniping underpriced auctions before other buyers notice them.

It runs while I sleep. I've woken up to emails about deals that sold out 20 minutes after being listed. Manual monitoring just doesn't work at that speed.

What's Next

I'm launching publicly on Product Hunt on February 24th, 2026. The roadmap includes SMS alerts, webhook integrations, and eventually direct integration with sniping tools like Gixen.

But the core mission is simple: make it possible to find the best eBay deals without sitting at your computer refreshing searches all day. I built it because I needed it. Now it's available for anyone else who needs it too.
