I enjoyed this, but as with most puzzles involving extra words there were several clues with a redundant word which did not appear in the extra word clues required. (Not the most felicitous sentence perhaps.) Without giving too much away, an example is 13 where the word "discount" is superfluous: the Chambers definition uses the word "voucher" unadorned as to its purpose. There were at least two others. Editors have to be stricter about unnecessary words where extra words are thematic. Having had my little grumble I confess to being stumped by 29. The last five letters are clear enough, but where's the definition? Is it an &lit?
