I was about to order these last week, but didn't get round to it. Usual price is £39.99 each. Buy 5 or more and it went down to £32 each. Logged on Yesterday to put the order in and they've gone down again to £24.99. So 8 of them have cost me less than £200 with free next day delivery.
Oh, and TCB just tracked at £3.49, not massive amount but everything helps.
