A reasonable translation from us $ to £ would lead to a price of slightly over £30 - you have to remember that US prices don't include sales tax (VAT in the UK). This still doesn't translate to £40, of course.... But, to be fair, the UK median wage equates to a higher level than us median wage... At the end of the day, you have to decide - is ttk worth what you are getting charged, regardless of what other people are being charged? We'd always like to pay less, but it comes down to what you are willing to pay. You can always wait, and then it will get cheaper.
