Trade selling prices allow Prybloxx to recover manufacturing costs and makea realistic contribution, with scope for the retailer to earn a further contributionfrom the final sale. The relationship between manufacturing cost andrecommended retail price is not linear. For example, the Basic Builder Kitcontains 153 parts and retails for V$44.99. The Master Builder Kit has twiceas many parts, but it retails for V$71.00, which is only 60% more. Prybloxxwishes to demonstrate that larger kits offer customers better value for money.Some prices are based on perceived added value rather than cost toPrybloxx. For example, the Motor Builder Kit contains the same number ofmoulded parts as Basic Builder, but it also includes an electric motor. TheMotor Builder Kit costs an additional V$2.74 to manufacture, but it retails foran additional V$15.00 because the motor offers much greater play value.Prybloxx also has limited capacity to produce those “added value” parts,especially motors and lights.
