I hate those things that are 'let us know if you don't want it' deals - you tell them you aren't interested in the first place and they just keep on and on about how it's 'no obligation' etc - then you have to remember to cancel - and there's the rub....
like the 'wonderful' insurance opportunities from credit card companies whereas they start billing you MONTHLY for insurance you didn't want in the first place - something like, 'we'll pay if your left thumb gets chopped on in an accident'.... duh
