[quote name='Littlefields']Like stackable? I don't exactly know what that means. Like for example if you register EGM websites all in one day your subscription will be more than a year?[/QUOTE]
Funny, mine is April 2010 also (if this works).
Yes, the free offers (and any you've paid for) should be stackable. I've done the EGM one, I guess, 4 times over the past few months (since April I suppose). You can only do each offer once, but these things come along frequently and if you keep doing them, they tend to stack (though others have reported getting multiple magazines sent each month instead). Just make sure you enter the same info each time (exact name/address). if you end up getting multiples you can probably clear it up by calling.
