Hello,
I’ve implemented a discount rule to variants product. It likes buying 2 product than fixed price 425 per unit.
The price is correct if I just select 2 quantities and add to cart.
However , if I add 1 quantity in S size then click 「add to cart」and add another 1 quantity in M size then click 「add to cart」, the subtotal is wrong. It supposed to be NT850 not NT980.
Even thought the subtotal in mini-cart is wrong, when I click shipping cart the price is correct.
By the way , if I refresh the page in URL: https://sunnyside.tw/cart/, the subtotal in mini-cart is correct again.
