I wonder whether the true availability was perhaps in a booking class that cost £10 more each way, and then a £10 offline fee was built into the base fare quoted. Or some other combination of similar circumstances. But I find these situations quite hard to debug unless the person knows what the original booking class and base fare were, and what they have actually ended up paying.
