    "```{admonition} Question\n",
    "\n",
    "I have 100 products in my store and each product has different price. I want to add discount on each product based on specific price. For example, If a product is added into the cart and it has 100usd price then i want to apply 10% discount on it and if a product is added into the cart and it has 110usd price then i want to apply 11% discount on it and so on. I hope you understand what I want to achieve. in simple words, discount on each product based on product price. Thanks\n",
