Fantastic 3 for 2 offer from Lonely Planet again
LP have been very generous over the last few months with their sales and offers.
The 30% off sale was just on and now (which I guess is the same thing but in a different form) you can chose 3 guide books to buy but only pay for 2.
You need to reach a total min order of $60AU and that will get you free shipping too
Please read the terms and conditions. No idea when the offer ends
