Harry, fair comment if English is not the applicant's first language. But when someone is challenged writing their native language, it suggests at least mild illiteracy, if there is such a state.
15 quid for a mass produced format that you can edit to personalise could be money well spent for someone who struggles as a wordsmith. But the OP is obviously quite literate, and said that it was 'expensive'. For such a person it seems like a waste of money to me.
