Competition.

Recently purchased an item. When checking out, there was an offer of a free gift on the eBay website. Clicked on the link, and was directed to a short survey about Bunnings. After completing the survey (6 questions) was advised to click on a choice of 6 boxes to see if I had won a prize, clicked on a box and was advised that I had won a Makita Power Tool pack worth $280. All I had to do was confirm address and pay postage.  Only option to pay postage was to enter credit card details. For $3.  Sorry I don’t think so. Curious to know if this was legitimate or not. Just seemed to good to be true.
