Pricing Manipulation
Sneak Into Basket
A small extra arrives in the basket with admirable confidence.
What is it?
The cart quietly adds an extra item — a warranty, a donation, a protection plan — without anything resembling an active choice.
How it works
The pattern changes the cost of thinking. It makes the preferred action immediate, emotionally charged, or visually dominant, while making the more reflective action slower, duller, or easier to doubt.
Visual Example
A simplified specimen designed to make the pattern recognizable at a glance.

Origin: Ecommerce, travel checkout, electronics retail, and donation flows.

Require explicit opt-in for every paid extra and make removal obvious.
