Which type of Shipping rates I can apply to the wholesale customers?
Wholesale All In One application allows you to setup 'Flat Shipping' rates. The Flat shipping rates charge a specific amount for shipping at checkout. You can create flat shipping rates for any order within a shipping zone, or only for orders whose weight or price is within a certain range.
For example, in a shipping zone for Europe, you could set a flat rate of $10, and another flat rate of $5 for orders that are over $50.
