I'm planning to purchase a whole list of books from book depository, which are going to cost a fair bit. The last time I saw a 10% deal coupon here was a while ago, so I'm wondering if there are any coupons going around at the moment by any chance?
Also, I walked into basement books yesterday and, after seeing some of the prices they had on their books, the prices I see on book depository didn't seem that crash hot any more. Obviously the range was very very limited, but still.
Might not be the exact answer you are looking for; use Booko.com.au to search for best prices, checks a range of online booksellers.
