Cheatsheets

The rules of a market, on one page each. Written from primary sources, dated, and honest about what could not be verified.

These exist because most of what gets sold as sourcing knowledge is a blog post quoting another blog post. Every sheet here names where it came from, says when it was checked, and lists the claims we could not confirm instead of repeating them.

Liquidation

Liquidation pallet contracts

Manifests are MSRP with no resale column, letter grades are cosmetic, and shortfall is measured on retail but paid on your bid.

Liquidation

Why $1 items lose money

A dollar single unit order loses about $4 on every channel that ships. The fix is pack size, and the numbers are here.

Amazon

Amazon ungating invoices

Ten of the same product, no ASIN needed, and the supplier type that fails no matter how perfect the document is.

Sourcing

Vetting a supplier

How you pay decides whether a bad deal is recoverable. Plus the resale certificate list everyone repeats that is wrong.

Electronics

Electronics sourcing channels

Most manufacturer refurb stores ban resale. The same companies run volume desks that welcome it, with the numbers to call.

Cash out

How buying groups work

Buy the deal on your card, ship it to their warehouse, get reimbursed, keep the points. And the four ways it goes wrong.

Ecommerce

The Shopify app math

A $49 app needs a 32.7% conversion lift at 500 visits to break even, and at that traffic you cannot measure it at all.

Crypto

Six checks before you buy a token

Supply concentration, bundled buys, deployer history, tax and sellability, liquidity, and the social layer.

More get added as they get checked. If a sheet here goes stale, it gets corrected on the page rather than quietly left up. What shipped and when is on the changelog.

The sheets are the rules. Inside is the live version.

Real deals with real numbers across every category, posted as they happen.
