Convenience comes at a Price

Many of us shoppers are being a bit more careful about what we throw into our shopping trolley; many items which seemed obvious and convenient just 12 months ago are now seen as expensive, a bit of a luxury. Heck-we can make that sauce ourselves. Heck-pasta only takes minutes anyway. We pay a price for convenience and that is our decision of course. But perhaps our banks and our corporations have become too much of a convenience for many of us and we need to keep an eye on them, a little more.
Anything else become so convenient we've lost the plot, a bit?
