Possibly because (a) a copy of the newspaper doesn't come with your membership and (b) if this is the standard on offer, it's not worth the money. There have been several instances of this recently with the ST cryptic. It's appalling that it appears to go unedited and unchecked.
The membership is just £25 a year. For that you get access to The Saturday Crossword, The Sunday Crossword , the TLS Crossword, both Jumbo Crosswords and the Club Monthly worth £100.
All of the above can be entered online, as I say saving money and effort.
Or... Buy a pencil! ( and maybe a Daily Mail subscription).
