^yes.
It becomes more difficult if someone does this for a full time living and hire people with warehouses.

Imagining scoring at least $300 to 400 dollar net profit average day per day for solo operation at home.

I am sure you guys knew me at first as a "belt guy" "safariland duty holster guy" or "5.11 guy" here about 10 years ago doing online price arbitrage.


One the the most impressive reseller doing this part time is a guy name Matt (part time picker).

By looking at 2 ebay stores he has, his ebay gross
Is about $16k per month. Imagine if he counts all platform such has fb marketplace, offerup, craigslist, etsy's, poshmark, amazon fba fba, etc.

He gets his merchandise about dime on a dollar.
ON TOP OF THAT, HE HAS A FULL TIME JOB.
