Hi,
Thanks for your patience, and thanks to the FOX team for the clear question.
The tiered pricing feature is our Dynamic Discounts module. There are two parts, and they’re worth separating:
1. The pricing table on the product page is rendered by XTS\Modules\Dynamic_Discounts\Frontend::render_dynamic_discounts_table(), hooked to woocommerce_single_product_summary (priority 25). It loads the template woocommerce/single-product/price-table.php (overridable in a child theme). The prices there are produced with $product->get_price() and wc_price(), so FOX’s standard woocommerce_product_get_price and wc_price filters already apply to that table. For layout, there are also two action hooks around it: woodmart_before_dynamic_discounts_table and woodmart_after_dynamic_discounts_table.
2. The actual price used at cart/checkout is where the currency issue comes from. Discounts are applied in woocommerce_before_calculate_totals, and the base price we start from is read with $product->get_price('edit'). The ‘edit’ context intentionally returns the raw stored price without running woocommerce_product_get_price which is the filter FOX uses to convert currency. So for the base currency (CHF) the result is correct, but for a converted currency (EUR) the tier is calculated on the unconverted base, which produces the wrong total.
To integrate FOX cleanly, we expose two dedicated filters in that calculation:
– woodmart_pricing_before_calculate_discounts( float $price, array $cart_item ) runs before the tier discount is applied. Convert the base price to the active currency here.
– woodmart_pricing_after_calculate_discounts( float $price, array $cart_item ) runs after the tier discount, if a final adjustment is needed.
A minimal example for the FOX team:
add_filter( 'woodmart_pricing_before_calculate_discounts', function ( $price, $cart_item ) {
// Convert WoodMart's base-currency price into the active FOX currency
// using FOX's own conversion helper, then return it.
return woocs_convert_to_active_currency( $price ); // pseudo — use FOX's real API
}, 10, 2 );
With the base price converted at woodmart_pricing_before_calculate_discounts, the tier discount and WooCommerce tax will both be calculated on the correct EUR amount, which should resolve the “VAT added on top for 2+ units” behaviour.
Let us know if the FOX team needs anything else on our side.
