Yes, they seem to charge different prices at different Premier marinas. Gosport Marina was 81p before discount. So I'm not sure what they mean by "sell it at cost"...unless it costs them more to sell it from a fuel barge than a land-based fuel berth /forums/images/graemlins/confused.gif
Depends on when the tanks were full. The fact that the price differs between marinas which will have different uses and fill tanks at different times suggest that the fuel geniunly is at cost, rather than an arbitury dicount across all sites
