No, I've just had word back from DD Hammocks - they won't be able to offer them at the prices I've quoted above for the number of orders I'm putting in I'm afraid - it'll work out more expensive than buying them direct from the shop. I've had one person who's going to the moot who wants a tarp which I should be able to fufil if he still wants it at the new price, but that's about it.
Sorry guys, if I'd been more organised a month ago I could probably have done this - the prices I'm being quoted are still good but not when you factor in parcel P&P which DD seem to offer for free.
