+# Price Gouging vs Shrinkflation: What's the Difference?
+
+You hear both terms used when grocery prices feel unfair. But they are not the same thing — and understanding the difference helps you know what to do about each one.
+
+## What Is Price Gouging?
+
+Price gouging is when retailers or sellers dramatically raise prices during a crisis, shortage, or period of high demand. It is most commonly associated with:
+
+- Hurricanes and natural disasters (gas, water, generators)
+- Supply chain disruptions
+- Public health emergencies
+
+**Example:** A hardware store raising generator prices from $500 to $1,500 the day before a hurricane makes landfall.
+
+Price gouging is **illegal in many states** during declared emergencies. Most states have consumer protection laws that prohibit excessive price increases when a state of emergency has been declared.
+
+## What Is Shrinkflation?
+
+Shrinkflation is when manufacturers reduce the size or quantity of a product while keeping the price the same — or raising it. The per-unit cost increases without the packaging change being obvious at first glance.
+
+**Example:** A cereal brand reducing its box from 18 oz to 15.5 oz while keeping the price at $4.99. The shelf price did not change. The unit price went up 16%.
+
+Shrinkflation is **legal** in the US. Manufacturers are required to disclose net weight, but they do not need to announce when a product gets smaller.
+
+## Key Differences
+
+| | Price Gouging | Shrinkflation |
+|---|---|---|
+| **Who does it** | Retailers and sellers | Manufacturers |
+| **When it happens** | Crises, shortages, emergencies | Continuously, as a standard practice |
+| **How it works** | Raising prices sharply | Reducing product size |
+| **Legal status** | Illegal during declared emergencies in most states | Legal year-round |
+| **Consumer response** | Report to state attorney general | Track unit prices; switch products |
+| **Detection** | Obvious price increases | Requires unit price calculation |
+
+## How CartSnitch Handles Both
+
+**CartSnitch tracks shrinkflation automatically.** We monitor unit prices across thousands of products and alert you when a product you buy regularly gets smaller or more expensive.
+
+**Price gouging is different.** CartSnitch does not currently detect price gouging — it requires monitoring retail prices during specific time periods and comparing against pre-crisis baselines. This is on our roadmap but not yet built.
+
+If you encounter what you believe is price gouging:
+- **Document the prices** — take screenshots
+- **Report it** — contact your state attorney general's office
+- **Shop elsewhere** — if possible
+
+## Can Both Happen at Once?
+
+Yes. A product could experience shrinkflation (getting smaller over time) AND be subject to price gouging during an emergency. For example:
+
+- A bottle of water that shrank from 24 oz to 16 oz over five years (shrinkflation)
+- The same product being sold for triple its normal price during a flood emergency (price gouging)
+
+Both are harmful to consumers. Only one is currently illegal.
+
+## The Common Ground
+
+Both price gouging and shrinkflation share a common feature: they exploit the fact that most consumers don't have access to real-time price data.
+
+CartSnitch was built to give that data to consumers. For shrinkflation today. For price gouging monitoring — and better tools for both — in the future.
