I am still smiling after the latest ploy I saw in Walmart. Snickers Bars, one of the most sacrosanct and popular American candy bars, just came out with big letters of the same font as their name, only instead of spelling out their name, they say: "Wimpy?" "Confused" and in some cases they are augmented with hazelnuts and my personal fave: chili powder. I won't link you folks to any of the promotional material but I did see that in the U.K. they are using terms that wouldn't be understood in the good ol' U.S., my favorite: "Stroppy" which I ran into in New Zealand.
I am sure that the first sales promotion came out the day after the first market debuted. or maybe hour.
