For a short time some of us stood on the corner of the street we grew up. During those long summer days we waited with eager hearts at the glimpse of each new car that turned the corner.  We were shocked to find that every single person in our neighborhood didn't want a taste of our lemonade. Although we didn’t seem to mind much then, looking back, why didn’t they want our lemonade? The answer: It’s not that they didn’t want the product we were offering, it’s that we offered no interaction and no incentive. You see it wasn’t the lemonade, although it may have been for some of us. Instead it was the approach. Alternatively, what if we had given out free lemonade on the first day only to offer coupons the next day? There’s the interaction. The next day we should have offered a $1 per-cup special. Included in the purchase is a handmade Crayola & construction paper coupon with a 10% off discount on the next purchase.  

Marketers call it experiential, we call it relationship-building! Hope this helps for your next campaign...Lemonade Anyone?
