Getting a trailer (burley cargo in this case, but applies more generally) has been a game changer. I can even bike to ikea and bring back flat packed furniture with it. Or do the weekly groceries. The trailer can carry up to 100lbs iirc (I have an e-bike)

Short errands are much nicer with a bike: less effort than walking, much faster than walking, no parking headache at destination, cool breeze in your hair, and free (no gas, insurance, parking, tickets…)
