1. When you make your first sale, follow-up with
customer. You could follow-up with a "thank you" email and include an advertisement for other products you sell. You could follow-up every few months.
2. You could upsell to your customers. When they're at your order page, tell them about a few extra related products you have for sale. They could just add it to their original order.
3. Tell your customers if they refer four customers to your web site, they will receive a full rebate of their purchase price. This will turn one sale into three sales.
4. When you sell a product, give your customers
option of joining an affiliate program so they can make commissions selling your product. This will multiply
sale you just made.
5. Sell
reprint/reproduction rights to your products. You could include an ad on or with
product for other products you sell. You could make sales for
reproduction rights and sales on
back end product.
6. You could cross promote your product with other businesses' products in a package deal. You can include an ad or flyer for other products you sell and have other businesses selling for you.
