On the face of it, $3 a month doesn't seem like much. But on the other hand, it is essentially free money. What would you do?
I'm just laughing at your question. Good luck!

Since you apparently do not already have an American Express credit card, and since I pretty much hate Capital One, I would get the American Express Blue Cash Everyday credit card. Actually, I did that approx. one year ago. Three bucks per month is 75 cents per week, so the benefit is not monetary. It may be beneficial to your psychological well-being, though, to have an alternative to Capital One. 
Like others, I would get the Amex BCE again, mainly for the additional benefits. If it was just the $3/month, probably not.
I use Amex offers and have saved hundreds with the complimentary shoprunner membership while ordering new struts online for a 20% discount (autozone was offering the discount only for items shipped to home, not store). I rarely need shoprunner, but it can be a very helpful option to have in your back pocket. I needed the parts within 3 days in order for the teaching auto shop to be able to fit me in for free, and I ended up replacing both front and rear struts/shocks with OEM or OEM-equivalent parts for under $300, on a job that was quoted well over $1K. Well, about an even $300 if you factor in gas and the 3 dozen chocolate chip cookies I baked for the mechanics as a way of expressing my gratitude. 
Having shoprunner made that possible.
Note that Amex BCE is pretty picky about which grocery stores get the 2% cash back. For example Whole Foods, a health food grocery store chain, isn't counted. Read the fine print on what's included. EDIT: see post below mine. either they changed it or I was just remembering wrong, sorry.
They also offer extended warranties on certain items you purchase. I've never made use of it, but it's enough to make me consider putting something on the card even if I get higher cash back with a different card, if warranty is important to me.
