I think this behavior should be legal. Capital One pays you to install their app to scrape prices. Of course they're scraping prices. It makes website owners mad because there's no IP address to block to prevent scraping, but if they really cared, they would make you request a quote and sign an NDA beforehand. Of course, sales would go to 0 if they did that, so they don't. The chrome extension is a happy workaround. One should be thankful that the big banks are spying on merchants and not you for once ;)
