What it is
A home-based business selling ink and toner online, plus a postal refill service where customers send empty cartridges and get them back refilled.
Your first three steps
- Choose a small range of popular printer models and source compatible cartridges and refill supplies from a trade supplier

Who pays
Households and small offices who want cheaper printing and prefer ordering online, including regular repeat buyers.
