Hello, I am new here so sorry if this has been discussed before but I was wondering if anybody remembers a nintendo trapper keeper type product? It was made of grey plastic, had nintendo markers inside,some other stuff, and came with a voucher good for a one year(or maybe 6 months) subscription to nintendo power? My memory is kind of hazy about the details but I remember buying these from shopko when I was young. Sometime around the first year or two of nintendo power. I remember that I made out very well when I found four of these on clearance at shopko for $2.50 each. I wasnt sure if they would expire or not but when each sub. almost ran out I would send another in and nintendo honored them each time. It was about the same size as a trapper keeper but it was more like a cartridge case that snapped shut. I would appreciate any info about this or a pic. thanks
