Embodiments of the invention described herein include low cost infusion devices having basal and/or bolus fluid delivery options. Embodiments of the device include a housing, a reservoir to contain the fluid, a source of pressure to exert a force to expel the fluid contained in the reservoir, a bolus port adapted to receive an optional extra dose of fluid, and a cannula in fluid communication with the reservoir and the bolus port. The cannula is adapted for insertion into the users skin for delivery of the fluid to the users body. The device can provide a continuous delivery of the fluid along a first fluid flow path from the reservoir to the cannula and the optional extra dose of fluid along a second fluid flow path from the bolus port to the cannula.
