Earny

Earny is an app where you register your credit cards and shop as normal and if a price lowers AFTER you bought an item, Earny will flag it and submit a cash back request on your behalf, often times with the originating credit card that has price protection. Stupid simple and they take 25% of the savings they actually get. I’ll come back later and talk more about this but for now, check it out.

Especially handy if you shop on Amazon.com where prices change constantly up and down. For that matter, if you want to know if the deal on Amazon is the best, check out camelcamelcamel.com
