Homebase Goodies?

Bank holidays are days that require an outpouring of our devotion to Mammon, or so is my understanding.

It would be good to give them a whirl, but I'm a cautious man. Anyone ever seen them and regretted/enjoyed doing so?

Also, here's a picture of my niece looking like Elton John:
