Is it Worth it?

I was just in Walmart, and they were giving away samples of 3 new soy meal bars (Soy Joy, 3 flavors). It made me think of a few questions, let us know your thoughts.

What do you think is more worthwhile for the Soy Joy company. 1) spending a lot of money on marketing for a few products that are average? or 2) Forgetting the average products and focusing on 1 good one?

Would Walmart make more sales if the head managers personally tested 20 products of the same genre and just gave samples away from the best one? Or do you think it is more worthwhile to give samples on many different items of the same genre.

Do you enjoy samples? Do they make you buy anything when you taste them or is it just "free food"?

Looking forward to hearing your thoughts...
