Quantity discounts for a mixed product selection using a specific product discount

[gasworks]

Hey guys/gals,

 

I'll try and explain what I'm trying to do:

 

if a user's cart contains a set minimum number of products, my client would like to apply product specific discounts to that cart's total. To be clear, the cart may contain any combination of different products but once the quantity clears a certain threshold, each product's discounted price should then apply, rather than the regular retail price.

 

I'm comfortable with displaying the unit price based on a "specific price" rule, however I'm less so in calculating the cart price if it involves hacking PS backend calculations given the unforeseen consequences that may result.

 

Ideally I'd prefer a solution via the interface or a plug-in module (I've looked, unsuccessfully), failing that class overrides if all else fails.

 

Thanks in advance

Solved this issue by amending /classes/Product.php:

$cart_quantity = self::$_cart_quantity[$cache_name]; 

to:

$cart_quantity = $context->cart->nbProducts() >= 6 ? 6 : self::$_cart_quantity[$cache_name];
