So my lady and I are doing an out of town bike century ride and I booked a room at Travelodge for $60 with a discount code from the ride organizer. She called to make sure they have internet access, and the operator offered us a $40 rebate on the room. It's one of those deals where you sign up for a service and pay $1 for the first month, and if you forget to cancel they charge you $16 a month after the first month.
Just to be sure I asked, "So I can sign up for $1 for the first month, you send me a check for $40, I can cancel anytime, and as long as I cancel before 30 days have passed you will only charge me $1?"
She said something like, "Yes, but we are confident you will enjoy the [whatever it was, I don't remember] enough to keep it."
So as I was signing up she offered me some other service, "Great Fun" I think, with the same exact deal. So I got that one too.
40-1+40-1-60= $18 profit to stay at their hotel and do a little work with the receipt, mail, and 2 phone calls to cancel. Sweet!
