I caught this article that discusses a study that states that if you let someone touch an item for a few seconds they're much more likely to buy it. I totally agree, because I've seen the touchy feely marketing strategy work great in automotive (test drives), bakeries (free samples), wireless (make free call) and a lot more industries. It simply works.
Try to get your prospects to use as many of their senses throughout the buying process/
What can you offer a prospect that allows her to touch, taste or try your product?
Do it and you'll close more sales.
