I complained days ago about this issue when my parcel was shipped. I strongly recommend you solve the custom duties payment. Most of the British sellers I have been shopping for in the last months apply pre-paid custom duties, I can give you many examples but for sure you know about them. Just for your information, I have paid 200€ on your online web and 90€ in addition to customs duties. You might imagine that this immediately removes you from my list for the next time if you keep this policy. I know maybe this is not under your responsibility but for a European buyer, this leaves you out of the market outside Britain. Thanks&Regards.
