This might get caught for VAT on entry to the UK but last week from the USA, a 400 pound cost item i bought got through without added tax. It seems Border control staff are on strike and despite a note from them saying there would be tax, it just came in the post tax free.
About 4 weeks to deliver the tank which comes with a quick release cap included. Very cheap for a large tank. I just have to trust they are fairly good at making these now and most feedback has been good. I will post progress when it arrives.
