I recently found a blog about the top 10 realtor closing gifts http://homebuying.about.com/od/realestateagents/qt/081607_RltrGift.htm

Listed at number 5 is:

"Spice Sets & Condiments
Quality spices, herbs and specialty condiments such as hot sauces from the Caribbean or barbecue sauces are delightful Realtor closing gifts to receive because they are useful and unique. After your agent samples fresh, quality gourmet spices, stale grocery-store brands will never hold a candle to your gift. "

Our gift boxes make the perfect thank you gift and some offer free shipping!
