What are we looking to do?

When you have an online store, by default a product has a set price which is what everyone pays. You may have discounts through voucher codes but occasionally you want to offer a different price to shoppers i.e. wholesalers.

So what we will be doing is creating a new role called 'Wholesaler', adding a new price field to our product, then we will set up a rule which will calculate the right price for the wholesaler.

The tutorial will be focused around a basic Drupal 7 install with the Commerce module (and the other relevant modules installed).
