Clear delivery terms reduce checkout exits
Delivery cost is a common reason for an abandoned cart. A buyer adds a product, sees a charge at the last step and leaves. The campaign paid for a visit that almost became a sale.
For example, a store with free delivery in Dubai and a charge for Fujairah can show both rules on the product page. The Fujairah buyer then decides before adding the item.
Your product pages can show the delivery time and cost for each emirate. This works because the buyer knows the full cost early, and the people who reach checkout are ready to pay.
