You too.
One other thought I had.
I you wish to buy and are worried about the import tax costs. I can send the t-shirt by GSP, you could send me the majority of the price as a separate payment i.e. send the me £90 by PayPal. I will then at an agree time & date drop the 'buy it now price' to say £9 + postage (GSP) and you buy it immediately. You will then pay the same price (in total), but I guess that any tax would be calculated on £9 not £99 (the paperwork (ebay) will show a price of £9), you will need to check with your tax authorities if this will work. Personally I don't understand why there would be tax on this as it's second hand. Normally (in the UK and Europe) tax is paid once on a product when it's new.
The risk with this is someone else does 'buy it now' if you are not standing by ready.
Perhaps with all this craziness, you can see why I normally just sell in the UK.
Have a think if this helps & let me know.
Best wishes,
