Volume Based Pricing

  We have base  price set in the system for all SKUs  (  item 7745  Price – 36.00 )

Price adjustment schedule, we set additional discounts also, ( discount 25%)   Net Price Billing -  27.00

Now – we need to go quantity viz discount –

From 1 pc to 12 pc     - $27.00 

From 12 to 24 pc        -$25.00

From 24 to 100+        $20.00

This is only one group of customer only. We linked this customer in a Price Group now
