If you have an established web site with a larger customer file, you can probably quickly parse through your database and grab e-mail addresses of repeat or best customers. As a token of your appreciation for their repeat business, offer them a special deal that no other customer can take advantage of (and let them know it’s exclusive).
This is typically done through an e-mail marketing promotion where a customer receives a coupon code for a percentage off, free shipping, etc. In the e-mail marketing promotion, let your customers know how to take advantage of the offer and when it expires.
