Personally I am a bit over online treasure hunts. Now this site just launched for Wrigley's Limited Edition 5 Gum Tin. It's eerily close to the M&M;'s Canada: Find Red campaign. You decide. Both are fun campaigns.
Good catch. One reason why M&M;'s wont mind their site being copies is because the parent company MARS owns both brands. MARS bought Wrigley back in 2008.
