1. Or perhaps a  because I don't know about you, but the only time I hate living solo in a walkable city is when I have to grocery shop and then carry said groceries up my stairs. (Ugh, I think I need this.) Even if you have just a few stairs at your home, this'll come in handy for trips from your car to inside the house post-shopping trip. It can carry up to 150 pounds and the wheels LITERALLY climb stairs. (As you can see here.)
