A device for dispensing a base substance and a booster substance in a user selectable ratio includes a dispenser head having a pair of spaced apart outlet ports, a first cartridge containing the base substance which is removably coupled onto the dispenser head and a second cartridge containing the booster substance which is removably coupled onto the dispenser head. Each of the first and second cartridges include a collapsible plastic liner which is mounted onto a supporting frame, the supporting frame of each cartridge having a uniquely shaped flange. A first pump assembly is disposed within the dispenser head and serves to draw a fixed amount of the base substance from the first cartridge and dispense the fixed amount of base substance out one of the outlet ports upon depression of a trigger which is slidably disposed in the dispenser head. A second pump assembly is disposed within the dispenser head and serves to draw a fixed amount of the booster substance from the first cartridge upon depression of the trigger, dispense a user selectable percentage of the fixed amount of booster substance out the other outlet port and return the remaining percentage of the fixed amount of the booster substance back into the second cartridge.
