@chris @jwildeboer yes, that is a great option. I used to do that a lot when I still hauled my groceries with my bike trailer. I actually took the trailer in to the store and loaded it directly from the schelves.
But since I moved to the mountains I do most of my shopping on foot.

@jwildeboer I actually like the self checkout counters. They allow me to properly pack everything in my trolley without pressure.
