Below is a copy of an email ,10/3/15, I was sent from Touratech UK regarding the cost of the seat.
It might be worth you doing an email to them to get some sort of competative pricing .
we are at present looking at our UK prices, as the Pound has got stronger and stronger, everywhere outside of the Euro has its own price for their country, we do need to have a higher price to be able to have a Touratech presents in the UK but of course see can see lately that this has crept higher and higher.
On this seat I’m happy to do it at the price of £386.46 inc and this includes Postage.
Let me know if you would like to order it.
Thanks and sorry for any problems caused.
