The price of aluminum cans as of November 11 2019 in Kansas is 30 cents per lb to 35 cents per lb depending on the scrap yard you go to.
The price of aluminum cans is not very high and to make the trip to the scrap metal yard worthwhile you need at least 20 to 50 bags of aluminum cans.
You can sell less amount of aluminum cans to the scrap yard but just taking a few bags of aluminum cans to the scrap yard is not really worth it.
I sell scrap aluminum cans myself but I wait until I have a trailer load of them to make it worthwhile and I try to wait until the price goes to at least 40 cents per lb if it does.
