I use An Post, Irelands reliable postal service to ship all orders.
At checkout you can choose from the following :
Standard Post: Reliable and cost effective delivery.
Registered Post: Provides secure delivery with tracking, signature required
Express Post: Next working day delivery with tracking, signature required.
For international orders please choose from standard post or registered post. I am currently unable to offer express post for international deliveries.
