gift card question - CALIFORNIANS ONLY!

i have a bunch of gift cards i’ve never used from target before. i used to live near one and shop there a lot and often get $5 gift cards from certain promotions that are going on. i don’t live close to a target anymore so i was thinking about cashing all of them out since in california they have to cash out a gift card if it has less than $10 on it. will it look suspicious to cash out a bunch of them and is there a limit to how many you can cash out?
