The best way to see pricing is to add items to your cart. All prices get updated based on your selections. For instance, choosing a bespoke or custom shoe last from the level of customization drop down affects cost. When ordering size runs (add various sizes of a style to your cart), discounts get applied automatically once items are in your cart.
Quantity discounts get applied after items get added to your cart and are as follows (per item, not cart):
2-5: 5%
6-10: 10%
11-15: 15%
16-20: 20%
