Many jurisdictions give you a legal right to cancel certain purchases within days of signing, with no reason required, precisely because those sales settings are built for pressure; know which sales are covered, and cancel in writing inside the window.

How to do it

1. 1Know the main rules. In the United States, the FTC Cooling-Off Rule gives you until midnight of the third business day to cancel sales made at your home (over 25 dollars) or at a seller's temporary location such as a hotel seminar, fairground, or restaurant (over 130 dollars). In the EU, the Consumer Rights Directive gives 14 days to withdraw from most distance (online, phone) and off-premises contracts; the UK has equivalent 14-day rules. Many US states add their own rights for gym memberships, timeshares, and similar contracts, and federal law gives three days to rescind certain loans secured on your home.
2. 2Know the gaps. In the US the federal rule does not cover purchases made entirely online, by mail, or by phone, nor real estate, insurance, securities, or most vehicle sales; there is no general federal right to return a car. In the EU, typical exceptions include custom-made and perishable goods, unsealed hygiene or media products, and travel or event bookings for specific dates.
3. 3At the point of sale, ask for the cancellation form and the written notice of your right. Under the US rule the seller must give you both; failing to do so is itself a violation.
4. 4If you have any doubt, cancel first and think afterwards. Send the signed and dated cancellation before the deadline by a method that proves the date (recorded post, or email where the contract allows it) and keep a copy. It is effective when sent.
5. 5Do not let a salesperson "pause" it, talk you into waiting, or start work or deliver goods early in order to get you to waive the right.
6. 6If the refund does not arrive in the legal period (ten business days under the US rule, 14 days in the EU), dispute the charge with your card issuer and complain to the regulator.

When to use it

• •Door-to-door sales: home improvements, solar panels, alarms, energy contracts, magazine subscriptions.
• •Sales seminars, hotel presentations, timeshare tours, and trade-show purchases.
• •Online and phone purchases in the EU or UK that you regret or that were not as described.
• •Helping an older relative who signed something under pressure in the last few days.

Evidence and how strong it is

This is a legal protection, not a psychological intervention. The FTC adopted the Cooling-Off Rule in 1972 after finding that high-pressure tactics were characteristic of door-to-door selling; the EU harmonized a 14-day withdrawal right in Directive 2011/83/EU. The behavioural rationale is well supported: decisions made in an aroused "hot" state are regretted once the state passes, and people underestimate this in advance (Loewenstein 1996). Evidence strength: the rights themselves are matters of law; evidence on how much they help in practice is limited and observational. Few buyers use them, largely because they do not know about them or because the seller makes the notice easy to miss, which is why this entry stresses asking for the form at signing.
