I just recently renewed my subscription to Fitness Journal, an on-line software that helps you keep track of exercise, diet, and various other fitness related things.
Today I received a hand-written thank you card and 5 tickets for a 30-day trial of the site. I have given away 2 but still have 3 available if anyone would like to try it out. I don't know if there are any strings attached or not. It doesn't say there is.
If you're interested email me and I'll send you the ticket number and the discount code.
