The free sachet of Squeek dishwashing powder on the cover of Gardening Australia this month is a lame tip-on. It has been used before, it is of little value and, as the photo shows, it is easily damaged when a browser puts the magazine back on the shelf. Tip-ons are meant to drive sales. The sachet of Squeek is a distraction for an otherwise good magazine. What does dishwashing detergent have to do with gardening anyway?
