Promotion at Tesco Direct at the moment for 500 extra clubcard points when you buy any Tesco Finest pans.
One of the included products is the blue griddle pan, which is also half price at the moment, down from £20 to £10. So, that's either an extra £5 off if you spend your vouchers instore, or £10 'profit' if you use your vouchers for Rewards (yes, I know some aren't truly 4x the value, but some are, it depends what you get).
The pan has been in and out of stock recently, but is in stock as I type. If it goes out of stock, I recommend signing up for the stock updates, and you get sent an email when it comes back in stock.
