The price you see on the Discover page or when you search for the product is the price of the product.
When you select the product you want and create an order, you will see the Pay Now price or the estimated Pay Later price you will pay for that product on the Order Summary page. These amounts include product price + delivery fee + Glocalzone service fee and state tax if you want the product from the USA or Canada.
In the Pay Now option, you pay at the prices you see on the Order Summary page. The prices in the Pay Later option are estimates and may change during the bargaining phase with the buyer. :)
