GAME are currently running a promotion combining their rewards programme with Skylanders Trap Team goodies at the moment. There's a whole host of information on it over on their website, but it looks as though you can nab a Skylanders trap by simply signing up to the Skylander Trap Team Club in-store at GAME.
HUKD user Gorilla26 posted that his brother had received a free water Trap as a result of signing up to the Trap Team Club, and we looked to clarify this with GAME, asking for clarification on the promotion and whether or not it's nationwide. Here's the statement we were given earlier:
"Hi Matt, yes this should be nationwide. Pls query with your local GAME store for further updates on this promotion. Many thanks."
We've followed up with a request for further information, and we'll publish here as soon as we hear more. As stated above, the promotion should be nationwide, but it's worth getting in contact with your local store to double check, and it may well be stock-dependent.
