If its over £36, you'll get charged improt tax, VAT etc etc to about 22.5% of what the package is worth + 22.5% of the postage cost. So for example, if your order contained £90 worth of stuff, and cost £10 to post you'd get charged £22.50. If its under about £40 they normally let you off, but if its serious dosh - they'll get you for it. Edit: Just remembered 'extra handling duty' about £8 regardless of weight/value.
