Unconventional marketing tactics

Imagine you are at Walmart and you have a Snickers bar in your cart. You turn your head to check on your kids, you look back at your cart and the checker has put 5 more candy bars in your cart and tells you how great of a deal it is. I then have to proceed to remove the 5 candy bars from my cart and say "No, I just wanted the Snickers bar"

Um. Thanks. But NO THANKS.

THIS IS TAKING IT TOO FAR.

BE SO GOOD YOU DON'T NEED CRAP TACTICS LIKE THIS.
