Yikes, I'm bad enough at procrastinating and distracting myself from this whole study business without any help!! I can't do next Friday, have to give a presentation (and hand in my dissertation!) but may be able to do Wednesday or Thursday, depending on whether I get some serious work done this weekend. And guess after that the half price thing stops....
Also don't forget you're meant to have filled out a form and sent it in BEFORE you go up the mountain to get the half price thing so does require some forward planning.
