Credit card price protection is a less well-known credit card benefit than saying, rewards, registration bonuses, and introduction rates. Price protection is a benefit that refunds your spread after the price of the item you recently purchased with your credit card has fallen. The difference does not have to be at the same retailer to get the benefit. So if you buy a laptop for $800 and then see it at another retailer for $600, you can file a claim with your credit card issuer and get $200.
