The Pre-Checked Box
"You bought something you never agreed to buy."
Pre-check upsells, insurance, donations, marketing consent, or recurring shipments at checkout, betting users won't notice.
Same hack. Three very different choices.
All optional add-ons start unchecked.
Inexpensive, easy-to-remove add-ons (a 50¢ donation) pre-checked transparently.
Pricey, hard-to-cancel add-ons (insurance, shipping protection, magazine subs) pre-checked.
A formula you can steal
Audit [CHECKOUT CHECKBOXES] → uncheck everything not explicitly chosen.
Where you've already seen this
- Airline checkouts pre-selecting 'travel insurance' for $35.
- Domain registrars pre-checking 'WHOIS privacy' as a paid add-on.
- Donation forms with the 'cover processing fee' box pre-ticked.
When the default is genuinely better for the user 90%+ of the time.
When the default extracts money or consent the user wouldn't actively give.
