Sneaking
Covert inclusion of products, fees, or commitments within a user journey without clear, upfront disclosure. This tactic relies on user inattention or interface complexity to avoid detection until late in the process.
Sneak into Basket
Additional items are added to the user’s cart without explicit consent, often as pre-selected add-ons.
Hidden Costs
Extra charges (e.g., fees, taxes, services) are only revealed at the final stages of checkout.
Hidden Subscription
A recurring billing model is embedded within what is presented as a one-time purchase or free trial.
