Delivery Pains

Don't want to deliver off the mainland?

For e-commerce businesses in the UK and the USA, non-contiguous /non-mainland deliveries can be costly as well as a real admin pain. 

In the UK for example, the Channel Islands, the Isle of Wight, the Isle of Man and Northern Ireland all have UK Postcodes and the Royal Mail charges standard postage prices for them all. However, if you use a courier other than Royal Mail for your business, these areas can be prohibitively expensive to ship to. This can lead to difficulties for retailers, either having to contact customers post-checkout to ask for a higher shipping fee, or else to make a loss on the delivery in order to keep the customer. 

The same is true for USA-based businesses and the non-contiguous states and territories. 

Luckily, Doctor Jock is here with just the cure! 

The latest update to our international address finder, the  Address Auto-Complete API, allows you to stop customers from entering addresses off the mainland in the UK and the USA at checkout.
