Exactly. This is one of those things like you'd see in a free-to-play MMO. Your character doesn't need a 3 day transparent mount, you don't need t-shirt and the mobile site.
But seriously. Just because your parents spent more money one seemingly more frivolous things does not mean that they should do so on this. Nor does it mean you should worry about spending it on the site. Hell, get them to buy you a shirt. Remember, just like playstation plus. They aren't giving you free games, just like how Whiskey media isn't giving you a free shirt.
First of all, if you really are a Beatles fan (especially at 15), that's just awesome. Hell, I'm 21 and that's young.
Second, I know you want to be a part of the club, get the cool t-shirt and all. But some things you just can't get. Really, the only thing you'll be missing out on is the Podcast (or at least, you'll get it a week late).
To be honest, just make sure you have your adblock disabled on giant bomb. That way you can still support the site.
