The t-shirt is actually worth £10 if ordered separate.
Posted by tommybuk - Used the live help on the site to speak to an advisor and can confirm that the shirt IS still included in the offer for now - the shopping basket / checkout just makes it a bit confusing, but provided you order the game then the shirt is free (and a size large).
This is actually cheaper than the normal version on Shopto.
