For those that haven't heard of Blurb, its a great way to make quality photo books. I've been using it for many years to create great travel photo books and I even printed my wedding album using Blurb.
They have just started a Refer a Friend program, so if you are a new user and make a book with Blurb, you will get 25% off your first order with this link — http://refer.blurb.com/go.axd?ref=NBRLOR
(This is an affiliate link as I will also get $15 credit)
Normally their discounts are around 15-20% off, so 25% off is pretty good.
Just looking at Blurb the other day. I found an interesting book by an artist that he (self?) published on here and seems not to be available anywhere else. I find it a bit expensive though (the link from his site advises US $88 and it $122 - might be temporary as it was on a few news sites recently) and am waiting for a good discount / reduction in price. http://www.blurb.com/bookstore/detail/2065724 The discounts I have seen are almost all for 'making your own' and not buying.
So if your buying try 'LOOKS' it says its a 'cascading offer' which I guess means not stacking?
I tried your refferal link but saw no changes in price - I had registered previously but not purchased.
Also buying directly from the US store is cheaper. I know the show 'Australian' prices but I don't see that they are printed or shipped from here (which would have been a big plus).
