tiered pricing, (as opposed to volume pricing)
Tiered pricing, but the price for the first items is set regardless of quantity. For example, if the price of an item is $750 for the first 5 and $600 for any items after, if an order of 20 items is placed, the price would be
5 x $750 + 15 x $600, instead of 20 x $600.

Thanks Thomas.
We have the same request.
The current Volume Based Pricing and Volume Discount Pricing is the same thing  just in 2 different forms. The final price calculated using either method will be the same. The only difference is what the customer sees visually.We would like to have a way to build pricing (similar to what Thomas has mentioned)
Tier (1 â€“ 1000) Unit Price (â‚¬ 3)
Tier (1001  5000) Unit Price (â‚¬ 2)
Tier (5001  10000) Unit Price (â‚¬ 1)
Calculation:
If a customer wants to purchase 500 units, the price is calculated as follows:
500 x 3 = 1500 EUR
If a customer wants to purchase 3000 units, the price is calculated as follows:
1000 x 3 + 2000 x 2 = 7000 EUR
If a customer wants to purchase 8000 units, the price is calculated as follows:
1000 x 3 + 4000 x 2 + 3000 x 1 = 14000 EUR
