Costa sell their syrups for £15 a bottle:. It's only £7 in Makro for exactly the same stuff, they must buy in such large quantities they get it for a steal, exactly what I thought when they asked for fifteen quid! I had to have it though so swallowed the rip off. They can go get stuffed now as I bought a stove top 6cup espresso maker, syrups and a flask.
The espresso maker fills my mug at home just nicely. In the flask at work I can enjoy it all day.
I think people buy Camp coffee for nostalgia, try some and put it on the shelf after they remember what it tasted like then offer it to visitors to use it up!
