Do you give a special gift (or set of gifts) to your buyers?
Do you give them a special experience during the buying/selling process in some way?
Do you make it fun for them some how?
I used to send a gift to my clients every year for Christmas. I had around 100 people so I tried to keep it under $15, including shipping. However, my company has grown and it's become too big of a task. Now we just send a card.
I also sent GC's to my clients at Christmas time. I did a $50 card to a nice local restaurant. I figured $50 isn't really anything when factored into the big scheme of things. My broker just got these nice chefs knives made, which have our brokerage logo on them. I think they were $75 a piece. Again, small price to pay when you're talking $1000-$10000 in commission per sale.
