Nintendo is offering retailers a chance to participate in a merchandising contest to promote the Pokemon Collectible Card Game's newest expansion, EX Team Magma vs. Team Aqua.  Retailers can build a smoking volcanic island (note the 'magma' and 'aqua' motifs) or create a great window or in-store display.  Participating retailers must mail or email pictures of their efforts to Nintendo by April 30, 2004.  Winners will be selected by May 15, and Nintendo is giving away some spectacular prizes including two Grand prizes, a Hawaiian vacation for two (airfare, hotel and $500 spending money), or a Custom PT Cruiser.  Ten other winners will receive an exclusive Pokemon retailer kit, which includes a 26' x 36' framed light box, a seven-foot Pokemon banner, plus play mats, t-shirts, posters, promo cards, and baseball caps.  Every retailer who enters will receive a mention on the Pokemon CCG Website, a window cling, two t-shirts, and posters.
