maybe ive just isolated myself for too long, but last time i checked, the 6 pack of soda was a common thing. i went into an AM/PM type mini mart today, and i found, to my suprise, no 6-packs of mountain dew in sight, instead there were just these 8-packs. i asked the guy behind the counter how long they had been selling 8 packs, and he didnt know. can anyone enlighten me as to when this change happened?
