A reference, not a course.

The Sales Archive collects sales techniques the way an encyclopedia collects facts. Each entry shows the technique as the actual exchange between buyer and seller, names where it comes from, and says how hard it is to use.

Most sales advice online is repeated without a source. Here, 23 books, papers and methods are cited across 93 entries. When a technique has no single originator, the entry says so instead of inventing one. When the famous story behind a technique is legend, the entry labels it folklore.

What it isn't

There is no coaching upsell, no webinar, and no subscription. The free entries are written to the same depth as the paid ones. The full archive is a single €39 payment.
