Have you ever wondered why you often find a coupon tucked inside your cereal box, or get invited to a customer preview sale at your favorite department store? Those companies know that their existing customers are the best - and most profitable - customers they'll ever have. So it's not surprising that they'll do whatever they can to keep these customers happy and coming back again and again.

Believe it or not, the same concept holds true for your art career. While you don't want to ignore potential customers, you'll find that when you pay a little more attention to the customers and collectors you already have, it will really pay off - in increased sales and profits for your art business. The following 10 practical strategies will get you started.

1 - Understand how and why your customers buy art

Put yourself in your customers' shoes. What's in it for them when they purchase your art? Maybe they feel great about owning a piece of original artwork. Or they're happy to support an emerging artist. Perhaps they're looking forward to showing their new painting to friends. Start listening to your customers and asking questions, and you'll learn a lot - fast.

Don't underestimate the power of being an art collector yourself. You'll know firsthand how your collectors feel when they purchase your work, and you'll be a great role model for them. Even better, you'll be supporting other artists.

2 - Make the first purchase a fabulous experience

When you sell a piece of artwork, remember that it's also an exciting event for your customers. So let them be excited about their purchase. Accept any compliments graciously. Then share something personal that lets them know that you're excited about the sale, too. Tell them how the sale is meaningful to you: It's your first; your first to someone in New Jersey; your first in this series, or your last one like this. A positive connection now can pay off for years to come.

3 - Be businesslike in everything you do

Treat your art as a business, and treat your customers in a businesslike manner. Be meticulous about meeting deadlines and keeping appointments. Always provide the materials or information you promised - complete, and on time. And remember to thank your collectors personally when they attend one of your shows or support you in any way. A quick note or an e-mail will be appreciated, and remembered.

In addition, be businesslike when you price your artwork. Keep your pricing consistent: from the gallery to your studio, and from city to city. And stick to your prices no matter what; never discount your work.

Naturally, it makes sense to present yourself in a professional manner every time you show someone your work. That said, never try to be someone you're not. Let your personality come through, and you'll be the best businessperson you can be: you.

4 - Make it easy for your customers to purchase more of your work

I was at a friend's house recently and admired a beautiful hand-made journal she'd purchased at a local craft fair. Thinking it would make a perfect gift for another friend, I asked for the artist's name. When she didn't remember, we looked inside the journal and discovered the artist's name and phone number were nowhere to be found. The result? He or she lost a sale.

Put your contact information on everything that leaves your studio: letterhead, invitations, show announcements, note cards, etc. Affix a personalized label on the back of each painting that includes your name, plus your e-mail address or Web site.

And send your new collectors home with an "Artist Pack": a professional-looking folder with your business card, resume, artist statement, bio, articles about you and by you, and so on. You
