Shopify/eBay/Amazon seller by day, AI builder by night. Sharing what I learn about AI + e-commerce — the real stuff, not the hype.

@bstocksol Bought a 'mixed auto parts' lot once and half of it was the same seatbelt buckle, 40-something of the exact same part. Still no idea how that happens.
@Catscollecttcg The notify-me list is the best pre-order signal you can get. Watching which of the three languages fills fastest tells you exactly how to split the reorder.
Most parts sellers race each other to the lowest price.
After 4 years, the listings that actually move are the ones with the clearest fitment info. Buyers aren't cheap. They're scared of ordering the wrong part.
@EcommerceBytes Losing the pre-2023 boards is bigger than it sounds.
That's where sellers worked out the fitment edge cases and the payment holds support couldn't explain, and next year someone hits the same wall and finds nothing.
Small claims means filing where eBay is - Santa Clara County - not where you are. Filing fees are lower but the travel cost offsets it for anyone outside California.
eBay changed its mandatory arbitration clause in its User Agreement to give it the right to force arbitration disputes to small claims court.

Buyer ordered the wrong-year alternator and wanted to return it. The part was fine, he just bought wrong.
Waived the restocking fee.
He came back for three more parts that month. Restocking fees teach buyers to remember the other guy.
@saen_dev Holds in auto parts - generic models trip on Civic Si vs LX rotors because my 4 years of fitment exceptions never land in their training set.
The weekly prompt for catching title vs description mismatches.
"Read this listing. Does the title claim anything the description contradicts? Quote the exact lines."
47 mismatches caught on the first run across my listings.
No unknown magic I’ve found yet, and I’ve tested a ton of hacks.
IThe real edge comes from stacking the fundamentals you mentioned: consistent daily listing, sharp photos, tight keywords, smart pricing, and top-tier service. For my website, revisiting meta titles, every now and then, based on google analytics has worked wonders at times
Tested listing brake parts at 9pm vs 9am for 2 weeks - 25 listings each.
9pm hit first-day views 22% higher. Total sales by day 7 came in within 3%. Early views aren't buyers. Sticking with 9am.
9pm listings got the quick view spike (22% more on day 1), but it didn’t turn into meaningful sales by day 7 (within 3%). Morning listings for me build steadier momentum with serious buyers (mechanics, weekend DIYers searching during the day). Plus, listing at 9am fits my workflow better for consistent quality photos/descriptions and batch processes
Buyer asked if a brake rotor fit his 2018 Lexus IS 350 F Sport.
Listing said IS 350. F Sport runs different specs. Asked for the VIN, sent him to a competitor with the right part. He came back the next week for shocks.
ANTHROPIC JUST DROPPED THE MOST SIGNIFICANT CYBERSECURITY ANNOUNCEMENT OF THE YEAR AND NOBODY IS TALKING ABOUT IT.
Claude Mythos. One month. 10,000 plus critical vulnerabilities found across the internet's most critical infrastructure.
Let the numbers land.
Cloudflare: 2,000 bugs. 400 high and critical severity.
Mozilla: 271 vulnerabilities in Firefox 150. Ten times more than were found in Firefox 148.
wolfSSL: Found a way to forge certificates on a crypto library used by billions of devices.
1,000 plus open source projects scanned.
90.6% true positive rate after human review.
At one partner bank Mythos prevented a fraudulent $1.5 million wire transfer in real time.
The UK AI Security Institute: first model to solve BOTH their cyber attack simulations end to end.
And here is the part that changes everything.
Maintainers are asking Anthropic to slow down.
Not because the findings are wrong.
Because they cannot patch fast enough to keep up.
Microsoft confirmed patch volume will continue trending larger for some time.
This one quote from the announcement is the most important sentence in cybersecurity in 2026:
"Progress on software security used to be limited by how quickly we could find vulnerabilities. Now it is limited by how quickly we can patch them."
The bottleneck just shifted.
For decades the problem was that humans could not find bugs fast enough.
Claude Mythos just eliminated that constraint entirely.
The new problem is that humans cannot fix bugs fast enough.
Which means the next frontier is AI that finds the bugs and writes the patches simultaneously.
That capability is months away not years.
The software security landscape is about to look completely different.

@Catscollecttcg Smart move - first listings on a new China exclusive usually go up at 2-3x retail. By week 3, early flippers tend to crash their price to clear stock.
