It's actually better than I thought. Minimum order is £25 with £5 postage. Postage free above £35. But the voucher counts against those totals, so I have just ordered 144 drinks at a cost of 12p each. If it were normally at that price level, I'd be much happier with it, but I can see myself putting in more of those orders, particularly as the decaff espresso is going to be impossible to get anywhere else.
