Post prices ?

Is the cost of posting packets and parcels going to kill ecommerce in Ireland. It is so expensive to post anything in Ireland it is hardly cost effective to buy small amounts in Ireland on the Internet. For example sugarfree.ie sells bars of chocolate on the Net but charges a flat fee of €5. All these small Internet companies have the same problem " the cost of deliveries " . The large companies can spread the costs but are also having delivery cost problems. Amoson UK has free deliveries on the Mainland but charge in Ireland north and south. The post offices around the world are loosing millions and making thousands redundant. They can't square the circle of cheap post with high overheads and fewer posting letters more positing packets and parcels.
