100 Greggs meal deals for the homeless

I would like to raise enough money to buy 100 Greggs meal deal gift cards to give to homeless people. A lunch deal costs £3.15 (less than your average cup of coffe from a coffe chain!) I'm far from well off myself, but right now, I have a roof over my head and food in my belly. Something a lot of people take for granted. I just want to provide at least one hot meal, for as many people who don't have that, as I can.
