How can I show appreciation to my customers? I am a distributor of items to businesses in a big resort city.? How can I show my appreciation to my better customers? What can I send over to their place of business for the "BUYERS" and the other employee's to share? I was thinking of a Fruit Basket? Any idea's or suggestions would be GREATLY appreciated! When I say BUYERS, I mean the people who place the orders, ordering from my company. Also, I don't sell Fruit, I was just thinking about getting it from another company and sending it over to them. Should I hand deliver it myself or have it delivered by the other company? Should I place a note? Should I include business cards with the gift??

Yes, gifts are important. Hand delivering is better than having a third party. Any means of conveying your appreciation which shows special effort on your part communicates the importance you place on their relationship with you.
