Discover has one of the best price protection policies in the business. Basically, if you find a cheaper price on an item you purchased within 90 days, they’ll send you a check for the difference. There are a few exclusions, but compared to the price protection policies offered by other banks, Discover’s is the most lenient and easy to use.
If you don’t have a Discover card or you’ve never used their price protection policy, you’re definitely missing out.
