I was in Woolworths on Saturday, their last day of trading and I must say it was a sad sight.

I’m not a big fan of the shop, it just didn’t grab me to be honest - I’m not sure why exactly but I would never have thought of going there to buy anything.  When I was younger there were a couple of shops I was interested in visiting - John Menzies and Woolies, however as time passed I realised Menzies had everything I wanted and so Woolworths drifted out of my life.

Imagine you are the head of a big company like Colgate or Persil or something like that.

You have one product, toothpaste or washing powder in their case, but then someone in your employ comes up with something a bit better - in the same line of product but it’s a toothpaste that helps prevent cavities better than the original did, or it’s a washing powder that helps prevent your colours fading better than the original.

What to do - do you simply replace your existing product with the new one?  Or do you keep making the old one, and simply put the new version on the shelves alongside it?
