bought a couple of spider-man t-shirts (and even a cool looking buttoned shirt) for my four year old a couple days ago and among the copyright tags, there was one claiming you could get 3 free comics.
Here'S a link to the offer:
www.marvel.com/3free
Bascially a 3 issue subscription for Marvel Adventures: Spider-Man, Ultimate Spider-Man, or Ultimate X-Men, that will not renew itself, where you only pay shipping charges, $3 ($5 for canadians).
You can also subscribe to 12 issues of some of their series for $18.97 ($28.97 for canadians) which seems to be a bit lower than their regular fee.
