I spend ages in the grocery store. Or, more likely, no time at all.
Because of shopping economics.

When my wife and I both worked parttime and alternated household and parental duties I made the most of the sparse moments alone when both kids were at school and preschool.
I made sure I got all the good deals and discounts, comparing weights, volumes etc.
That took time, but by practice I learned to do it more efficiently.

Nowadays I'm the only one that brings money in so I do a lot less shopping. And when I do I still feel obliged to make the most of it - but the products have changed, their locations have changed, all the prices are different - I walk up and down the aisles only occasionally grabbing bounty.

Likewise, my wife got better at it. So we really need a good reason for shopping duties to fall on me. Added bonus is that it lets me avoid the local shopping trips where I need the car (which I try to avoid) that are so detrimental to my average fuel consumption. Vain, me?
