High 5 Gel Powder - where are you?

Does anyone know where I can buy High 5 gel powder on-line? I had a tin a couple of years back and found it great for long runs with a gel bottle. Last year I tried to re-order some and was sent an energy drink instead so ended up carrying the gel sachets around a marathon. This year I have searched high (!) and low - I placed an order with one site that appeared to have some but they have not sent it, have no record of my order and won't answer my emails! I checked again the High 5 website and it seems to have disappeared. I really would like to get my hands on an illusive tin before the Jersey Marathon in October.
