Some supermarkets have extra large shopping carts to seduce us into buying more stuff.
After all, an empty looking shopping cart somehow just doesn't feel right.
Especially when everybody else's has a lot more stuff in it than ours.
So we end up buying a lot more stuff than we really need to.
This of course doesn't apply to shopping carts only.
It applies to pretty much everything in life.
So if your cart somehow feels too big, just take a smaller one...
