Double stroller or no?

I can’t decide if I want to get a double stroller or not. I live out in the country and 25 minutes from the closest grocery store in any direction. My dilemma is is that where I grocery shop is a college town and has activities for kids to do outside so I’m wanting to get back to going on walks around town on Saturday mornings and then head straight to the grocery store like I used to with my son before I lost all my energy and motivation with this pregnancy. The only problem is how do I do all that with a 2 year old who can’t be trusted to walk next to me and an infant who obviously can’t sit up in a cart? Any suggestions on double stroller that are easy to push around town and lightweight and aren’t super bulky? I tried grocery shopping with my son while wearing him in a carrier but once he was about 4 months old he was just too big and heavy for me to do that and I’m assuming this next little boy is going to be the same way. ( it’s in their genes to be big) maybe it was just the carrier I used not being the best for the job. I felt like he wasn’t steady enough and that I constantly jerked him around in it.
