Actually they seem to use the same idea as P1. The price works out at £60 per day on the basis that 3,000 provides 50 days. Not bad. They must expect a high utilisation %. It should be possible to bring something like this to a wider audiance though.
I thought I'd read somewhere that they were struggling though??? - not sure, but most businesses are struggling in the current climate, apart from take-away joints and Aldi!!!
