I don't know about you, but I hate carrying my groceries to the door in my garage, and making that trip SEVEN TIMES! It's too repetitive and tiring, and time-consuming.
So, instead of you carrying the grocery bags, why not have the grocery bags carry themselves? In other words, put them on a conveyor belt in your garage that automatically delivers them near the fridge. May be tied to the garage door system that opens the garage. Possibly hanging each of the grocery bags on hooks that bring it through the garage and into the house.
