Are there any active signup bonuses for Capital One Shopping?

My parents saw something online about Capital One Shopping having good cashback bonuses this holiday season and asked me about it. I remember when I signed up for the app back when it first came out, there was a signup bonus of $45 or something like that; is there something like that still going on? I figure if my parents want to sign up, might as well see if they can get a bonus while doing so.

Thanks!
