Okay, so I got an email about Boca Java today. I've never done an offer before (newbie) so do I click on the Boca link from my email to sign up for the offer? Will it just know my SR number? Can I cancel before the 4 week time is up when they send you regularly-priced coffee?

I looked through some of the threads, but did not find my answer, although maybe that's because it's obvious and I can't see it!
