1. A fluid dispenser comprising two reservoirs, two pumps, and two pushers, namely a first pusher for actuating a first pump that is connected to a first reservoir containing a first fluid, and a second pusher for actuating a second pump that is connected to a second reservoir containing a second fluid, the dispenser further comprising a third pusher for dispensing a mixture of the first and second fluids, the first fluid being dispensed through a first dispenser orifice, and the second fluid being dispensed through a second dispenser orifice, wherein the mixture of the two fluids is dispensed through a third dispenser orifice that is formed by the third pusher; and wherein the first pusher is distinct from and independently actuatable with respect to the second pusher; and wherein the third pusher is mounted on a third pump that is connected to the first and second reservoirs. 2. The fluid dispenser according to claim 1, wherein a buffer mixing reservoir is interposed between the third pump and the first and second reservoirs such that the third pump is connected to the first and second reservoirs via the buffer mixing reservoir. 3. The fluid dispenser according to claim 2, wherein the buffer reservoir is connected to the first and second reservoirs via two ducts, each fitted with a respective check valve, the fluids being sucked by the third pump into the buffer reservoir through the ducts. 4. The fluid dispenser according to claim 1, wherein the third pump includes two dip tubes that extend in the first and second reservoirs respectively. 5. The fluid dispenser according to claim 1, wherein the first and second pumps each define an internal vent passage that is opened by actuating their respective pushers, the third pusher pressing lightly at the end of its stroke on the first and second pushers so as to open the internal vent passages of the first and second pumps. 6. The fluid dispenser according to claim 5, wherein the third pusher includes a collar that projects outwards above the first and second pushers, the axial distance between the collar and the first and second pushers being a little less than the stroke of the third pusher. 7. The fluid dispenser according to claim 1, wherein the first and second pumps each define an internal vent passage that is opened by actuating their respective pushers, the third pusher pressing lightly at the end of its stroke on the first and second pushers so as to open the internal vent passages of the first and second pumps. 8. The fluid dispenser according to claim 2, wherein the first and second pumps each define an internal vent passage that is opened by actuating their respective pushers, the third pusher pressing lightly at the end of its stroke on the first and second pushers so as to open the internal vent passages of the first and second pumps. 9. The fluid dispenser according to claim 3, wherein the first and second pumps each define an internal vent passage that is opened by actuating their respective pushers, the third pusher pressing lightly at the end of its stroke on the first and second pushers so as to open the internal vent passages of the first and second pumps. 10. The fluid dispenser according to claim 4, wherein the first and second pumps each define an internal vent passage that is opened by actuating their respective pushers, the third pusher pressing lightly at the end of its stroke on the first and second pushers so as to open the internal vent passages of the first and second pumps. 11. A fluid dispenser comprising: a first reservoir in communication with a first pump for dispensing a first fluid into the atmosphere from the first reservoir through a first orifice, the first pump actuated by a first pusher;a second reservoir in communication with a second pump for dispensing a second fluid into the atmosphere from the second reservoir through a second orifice, the second pump actuated by a second pusher, the second pusher is distinct from and independently actuatable with respect to the first pusher;a third pump actuated by a third pusher for dispensing through a third orifice a mixture of the first fluid and the second fluid received from the first reservoir and the second reservoir, respectively, the third pusher is distinct from and independently actuatable with respect to the first pusher and the second pusher; andwherein the fluid dispenser further comprises a third reservoir in communication with the third pump and containing the mixture of the first fluid and the second fluid received from the first reservoir and the second reservoir through respective fluid conduits.
