Is it permissible for a seller to inform the buyer of a delivery price lower than the actual price, and bear the difference from the original product price, in order to attract customers if the delivery price is high?

It is permissible to buy and sell online, provided that the sale occurs upon the customer's receipt of the item and payment of its price, or that the item is present and its description is accurate. However, delaying both the price and the item is not permissible. Regarding delivery fees, it is permissible to inform the customer that delivery is 500 riyals if that is truly what the buyer will pay. The item can also be sold with delivery at an inclusive price without detailing the delivery fees. Selling an item with the condition of delivering it to the customer is permissible if the benefit is known, such as combining sale and lease.
