The Free Card
"Free isn't 1¢ cheaper than 1¢ — it's a different category."
The brain treats 'free' as risk-free. Switching from 1¢ to free disproportionately spikes uptake; the same difference between $1 and $1.01 is invisible.
Same hack. Three very different choices.
The free thing is genuinely free, with no required follow-on payment to use it.
Free + shipping where shipping is the actual margin.
'Free trial' that requires a card and silently converts to a charge.
A formula you can steal
Make [SOMETHING SMALL BUT REAL] truly free → use [LARGER PRODUCT] as the upsell.
Where you've already seen this
- Amazon Prime free shipping over $25 — drove the original Prime adoption curve.
- Hershey's Kisses outpulling Lindt truffles 5-to-1 when both dropped 1¢ to free in a behavioral econ study.
- Loom's free 5-min videos — no card, no expiration.
When you can give a real, useful version away with no card and no expiration. The 'free' must survive scrutiny to do its work.
When the free version is functionally a demo. Users now sniff this out faster than ever and resent it loudly.
