Because I remember the author's thread about getting more karma, I'd suggest that the odds of this story being successful on Hacker News are diminished by the promotion of a marketing gimmick in the headline.

It turns the post's intent from a 'here is something that might be useful for you' to 'here is something that might be useful for me, the author'.

Good luck.

thanks for the feedback - still looking for the most effective ways to share useful content.

Just share the content. What am I going to do with a hundred quid in Alabama?

haha, understandable.

Pret is dismissed early in the article, but having previously been an espresso lover, I'm now hooked on Pret's filter coffee. At 99p a cup it has the best bang for buck of any takeaway coffee, and although I occasionally encounter a rough batch, it is usually more flavoursome than most espresso based beverages.

Pret's filter is superb! I wasn't dismissing, it's a great fail safe, and they're everywhere.
