A few numbers, based on this being an 11"x13" book, hardcover.
Standard price is £30.95 but for quantities 10 & over, there is a 10% discount - so that's £27.86 each.
Shipping:
1 copy - £3.99 / £34.94 total (no quantity discount)
2 copies - £3.99 / £32.95 total (no quantity discount)
3 copies - £3.99 / £32.28 total (no quantity discount)
10 copies - £24.27 / £2.43 per copy / £30.29 total
15 copies - £35.78 / £2.39 per copy / £30.25 total
20 copies - £48.50 / £2.43 per copy / £30.29 total
The downside is that there then also needs to be another carriage charge to get the books from here to wherever they're going within the UK as they have to be sent from Blurb in one shipment.
I can't quite remember how much that was, but it's going to be in the ballpark of just over £4 per copy.
Thus, we're probably looking at a minimum of £34.50 a copy and if it were done as a fundraising exercise it would have to be something like £39.95 in order to generate a decent sum from a (fairly limited) run of 20 copies.
There are thus probably two or three options and I'm happy to open them to debate:
(i) we order a batch, sell them at £34.95 and distribute them from within the UK, with no donation to charity (if there's anything left over, it could be invested in a few bolts for some unspecified project)
(ii) we order a batch, sell them at £39.95 and distribute them from within the UK, with a donation to a mining-related charity which will be perhaps £75 in total
(iii) we can open the book up for direct ordering on Burb and allow people to order as and when they like - the price will be £34.94 but if a couple of people order books together, the flat rate of carriage at £3.99 works for up to three books and that can bring the cost down to £32.28 per copy
Thoughts on a postcard... 🙂
EDIT: the carriage from Blurb to the UK may be subject to VAT, can't quite figure it out from their website...
