Amazon
1. Urgency and Scarcity Tactics
- "Only X left in stock" messaging, even when inventory levels are higher
 - "Order within [countdown timer] for delivery by [date]" creating artificial time pressure
 - Flash deals with countdown timers to drive quick, less-considered purchases
 
2. Misleading Price Comparisons
- Displaying inflated "list prices" or "was" prices to make current prices seem like better deals
 - Bundling items with "savings" that aren't actually savings when items are purchased separately
 - Using "Prime Price" vs regular price to make Prime membership seem more valuable
 
3. Subscription Manipulation
- Pre-selected "Subscribe & Save" options that default to recurring purchases
 - Making it deliberately complex to cancel Prime membership with multiple confirmation screens
 - Hiding the annual subscription total by emphasizing monthly payment options
 
4. Hidden Costs and Options
- Not showing full pricing including shipping until late in checkout process
 - Burying free shipping options beneath paid expedited options
 - Making "no rush" shipping benefits less prominent than premium options
 
5. Interface Misdirection
- Making "Buy Now" buttons more prominent than "Add to Cart"
 - Using color and size hierarchy to emphasize sponsored products over organic results
 - Placing ads in search results that look nearly identical to regular product listings
 
6. Choice Architecture Manipulation
- Presenting Amazon-branded products prominently in search results
 - Making it difficult to compare prices across different sellers
 - Using default sorting that prioritizes items profitable for Amazon rather than best for customers
 
7. Data Collection Pressure
- Persistent prompts to enable personalized recommendations
 - Making opting out of data collection more difficult than opting in
 - Using social proof ("Customers who bought this also bought") to encourage additional purchases
 
8. Cart Manipulation
- Adding suggested items to cart automatically with some purchases
 - Making it less obvious how to remove items from cart
 - Emphasizing "savings" on bundled items even when individual purchases might be cheaper
