Hi, I'm using Prestashop 1.6.1.18
When I click product, base price (1,550,000 đ) displayed exactly, but I add 2 items, price change to 2 đ. I add more 3 items, price display 2 đ only.
But when I go to check out page, product's price display exactly 1,550,000 * 2 = 3,100,000.
How can I fix this problem?
Please help me~
