I am having a difficulty due to our pricing construction I hope somebody will help me out.

We promote heavy objects thus making a visit to 1 location for 1 merchandise is dear. So so as to encourage clients to purchase 2 objects for cheaper supply, we provide reductions.

1 merchandise solely, supply $30
For two or extra objects, supply per merchandise $15

The merchandise is a variable product and vary from $100 to $200.

I explored a couple of plugins however none appear to fulfill my necessities.

Any options from WC customers?
