After a mistake (ours) on ordering for a friend's birthday the package arrived at our house instead of London.
We called the stop and they could not have been more helpful.
A second package was dispatched immediately and arrived in London on time.
Diolch, we also got to sample what we had bought for our friend, 'every cloud' as they say.
The only thing to be aware of unless you change the default address on the website to your intended recipient it seems to change the delivery address back to the purchaser.
