Apology: shipping charge error

Apologies. I can see some orders are arriving with shipping charges that are double or even triple what they should be. If you get to the checkout and the shipping charge appears ridicilous please get in touch. I will try and get this resolved in the next 24 hours. Wherever this occurs we will credit the overcharge back to you. It appears to be related to having multiple items in the shopping cart, but only for certain combinations of items.
