The pricing that is listed in the right hand column of the product descriptions is for a Baseline design. This baseline design price listed is typically for the classic oval or rectangle shape that has a large barrette clasp. If the overall shape is more complex then the classic oval or rectangle, when the item is added to the shopping basket, the price will be increased. This increase depends upon the complexity of the selected design.
Also, if S, M or XL is selected, when the item is added to the shopping basket, the price will be increased or decreased.
This may seem a bit complex; however, the shopping basket takes care of the complexity and adding or subtracting from a Baseline price keeps my barrettes more competitive and more reflective of what each individual barrette costs.
