I built a $350,000 eBay inventory sourcing estate sales with a phone and a system. First 100 Flips is that system — sourcing, research, listing, storage, shipping — written down as a day-by-day plan, with my real numbers attached to every claim.
Built to pay for itself within 2 weeks — or your money back.

Read This First
I've watched it happen over and over: someone buys a trunkload on gut feeling, writes listings nobody finds, lets inventory rot in boxes, and walks away the first slow week. None of them lacked talent. They lacked a system. First 100 Flips replaces every guess with a checklist and every "maybe" with a number. You bring the hours — the plan already knows what to do with them.
You don't get "tips." You get orders: today you source here, research this, list these, ship by this time.
Exact buy prices, minimum profit floors, sell-through thresholds. You'll know an item is profitable before you touch your wallet.
Every flip funds the next two. By flip #100 you're running entirely on the house's money — not your own.
Do every checklist for 30 days. If the system hasn't paid for itself, I refund every dollar.
Receipts, Not Promises
Every item below came out of an estate sale or a dig. Six of the ten were spotted in the sale's own listing photos — from my couch, before I ever showed up. That method is Module 4, and it's why this page doesn't need stock photos.

I'm Byron — I run Finest LLC on eBay. I'm at estate sales five days a week, Wednesday through the weekend, working the exact circuit this course teaches. No rented Lambos, no screenshots of other people's dashboards. My store is public, my sold listings are public, and everything in this course is something I did this month — not something I read about. Watch me work on Instagram or TikTok.
The Five Skills
Everything you asked the internet and got half-answers for. Covered completely, in order.
Thrift stores, garage sales, estate sales, bins, clearance, auctions, and free stuff — ranked by profit-per-hour, with exact routes and what to grab first.
The 60-second comp check that tells you what anything is worth, how fast it sells, and the most you're allowed to pay — from the store aisle.
Keyword-stacked titles, the 8-photo formula, item specifics that rank, pricing strategy, and which platform wins for every category.
The SKU bin system: any item found in 10 seconds, zero death piles, scales from one shelf to a garage.
Cheapest label every time, damage-proof packing with free supplies, and the 48-hour ship rule that builds a 5-star reputation.
The Payback Math
No hype — arithmetic. Phase 1 of the plan starts with items you already own, so your first sales are nearly 100% profit.
Ranges based on common household resale categories following the listing system. Your results depend on your effort and items — which is exactly why the guarantee is tied to doing the work.
The 90-Day Hardcore Plan
Four phases. Every phase has weekly targets and daily checklists. Print the calendar, put it on the wall, check the boxes.
House Audit pulls 15+ sellable items from your home. You learn research, photography, and listing on inventory that cost you nothing — so every mistake is free and every sale is profit.
Profits from Phase 1 become your sourcing budget. Guided thrift and marketplace runs with the Buy/Pass framework, strict price caps, and beginner-safe categories only.
You install the operating rhythm: listing quotas, the SKU storage system, batch shipping days, and the send-offer routine that clears stale inventory automatically.
Your tracker now holds 100 data points. Module 9 reads them with you: which categories print money, which to drop, and whether your next move is niching down, scaling up, or going full-time.
Inside The System
Each module ends with a non-negotiable action step. You don't move on until it's done.

Also From Finest Flips
Estate sales are where I find the home runs. Storage units are how I buy in bulk — entire households for one bid. Bidding strategy, reading a unit from the doorway, hauling, and turning one locker into a hundred listings. For flippers ready for bigger swings.
