HTC's website is very strange. This is worrying:
Great. 'May' apply?! This is in the FAQ section of the UK store?!
Also, how do you contact them by phone? I'd like to change the payment method but the only phone numbers given are Irish numbers?!
Wow, this is a total mess. Just went to re-order and at first it was fine, accepted the code and quoted £512.99. Entered card information, got to confirmation screen - £569.99. So tried again and now it quotes £569.99 but adds it to the cart priced in Euros even though I'm using the UK site? It also doesn't list the UK as a 'Shipping Country' anymore. What on earth!?
Tried it on another machine, looks like it auto removes the discount at checkout if you've already had it. So unless I make an international call it seems to I have no way of changing my payment method. Incredibly bizarre for a company allegedly trading in the UK.
