Gregg's reusable cups £2, free coffee and 20p off future drinks

Hi,

Sorry if this has already been mentioned, I did a search and couldn't find it if it has

I picked up a Gregg's reusable travel mug today. £2 with a free coffee, making it 45p.... And they gave me a stamp on my card (collecting for a free coffee) and I'll get 20p off future drinks when I use it.

I can hold it, full of hot coffee, without burning my hand. I've ditched the other one I had.
