Give someone else the credit

When I want to recommend something to a customer I usually give someone else the credit. Instead of saying "I think you should use a coupon in your ad." I will say "A lot of my other customers like to use a coupon in their ad, what do your think?" This adds credibility to the statement. People are naturally suspicious of sales people (They know why you're there). Putting your words in someone else's mouth makes them much more believable. This also serves as a form of a testimonial since it reminds them that other business people just like themselves used the idea. This is a simple technique but I have found it to be quite effective.

Keep Smiling, Keep Selling!
