Buy the three pack of Quattro for women blades, and get the razor free. Absolute steal considering the razor alone is £10.79 in Boots! I found this in the Tesco Express in Cleveleys, but I expect it is nationwide as it is a multibuy discount that comes off at the till with a yellow link save offer on the shelf.
Sorry if it has already been posted. Please let me know if it is in your local stores, it doesn't seem to be online. I'll post the receipt in the comments :)
