Instructions:Just noticed an offer on the back of the takeaway menu in Pizza Hut giving £5 off a £15 order (excludes offers). The staff weren't too clued up on the offer and I had to mention it myself but I got a large pizza, chicken wings and garlic bread for £10!! Better than the meal deals they offer. I presume this is available with delivery pizza too - probably worth checking first though.
(Hope I've done this right - it's my first deal)
