Mozi, one of my favourite Australian design brands, has just announced a special offer for August - a free postcard book when you spend $40 or more at the online shop. This is very easy to do as the Mozi products are gorgeous! The postcard books (one of three designs) contain 21 occasional postcards including seven 'happy birthday', seven 'thank you' and seven blank cards and normally retail for $15.95. Prices are in $AUD and Mozi delivers internationally by weight. (International sales receive 10% discount as GST is removed).
P.S.: check out the sale section; the tea towels are fantastic.
