Re: The Wolverine merchandise
So far the merchandise is limited to the Trask Industries Cap and promotional posters that were distributed at Comic Con. Currently, they are on eBay, and I would recommend picking them up before the supply runs out and price rises. I got my Trask cap for $5, including shipping.
