I know there is a plugin to manage price per quantity in VirtueMart (and I already bought it) AND I know that since v2.0.18 multiple prices can be set for each product.
Now I have the need to set price per quantity for custom fields of "Cart Variant" type.
Example:
Range | T-shirt Price | Blue t-shirt Price |
1-10 | 20 | +5 |
11-20 | 18 | +4 |
Do I have to write a VMcalculation plugin? Is there any pointer to similar plugins? Are there better solutions?
Thank you for any suggestion.
