Hi, Traverse,
With that list you would need:
EE+MSM (3 Sites)
EE
EE
So you will get a Volume Discount.
Each software purchase you make on the same expressionengine.com account is logged so that as you meet milestones as indicated below you will automatically receive the discount. The discount plan is cumulative, allowing you to purchase what you need today and still receive a discount when you meet any of the milestones at a later date. Please note that the volume discount plan only applies to ExpressionEngine and ExpressionEngine module purchases. It does not apply to 30-day demo sign-ups or Additional Sites for the MSM.
Volume Discount Milestones:
3+ purchases, 10% off
6+ purchases, 15% off
10+ purchases, 20% off
15+ purchases, 25% off
20+ purchases, 30% off
30+ purchases, 40% off
40+ purchases, 50% off
