"Could you get DH to leaflet everyone on his rounds? " done done done (he's only got 400 rounds, and other posties have also helped, but they're allowed to help if they choose to and not to take the piss - which means that Christmas catalogues is more than enough)
"Approach some of the new free schools, they might not have their books sorted out? " - have done that - I do a mailing out to all the schools every term or so (fed up of them ignoring them quite frankly)
All the new free schools in this area are academies made out of existing schools. There is a company (one-man band) that supplies secondary schools and I've teamed up with her (because it's cheaper for her to buy books from me from my supplier than it is for her to buy the books directly) in the last few months. I might keep doing that with her when she closes. (it won't be a "wage" though)
I'll look at your suspended books thing
music My stock is worth is worth about £40k at cost. I will still have the overheads to pay until I close as well as selling the stock. can't afford to do less than 30% discount really (probably even 25% is maximum) in order to pay for everything that needs to be covered.
MrsK - school fetes are a waste of time round here - they give me a stall, right next to a second hand book stall selling books at 10p each! then they wonder why I don't get more sales on the day! 
even when there's not another bookstall, parents send their kids in with a couple of quid, they don't want to pay shop price for a book (for favoured schools, I will put special prices on, but that makes the books so close to Cost that there's absolutely no benefit in doing it)
and yeap, no cover for the shop!
SuperMum - can't sublease space, not allowed in contract. no point ending the lease early, I need time to sell the stock (and there are a couple of events in the summer coming up) besides which, I don't actually want to close, so closing early would just be too much to handle, emotionally.
Inventory changes every day, so would be a total waste of time. I have a database (an Epos system) so I know everything that comes in and everything that goes out - I don't need a spreadsheet.
I don't want a job - I've got a 17mo that I want to be with. If I got a job, I'd just be paying out for child care.
I want to be upset. I have put my entire life-savings into this shop (not to mention every ounce of passion and love that I have)
