20% off book packs, free encounter guide(save $20) PLUS cashback @ Lonely Planet
I think this is a pretty good deal.
First you get the guide book pack. They have a few to chose from eg Africa, Australian, Peru travel pack .... and this saves you 20% on what you would pay for the books separately.
You then can grab an encounter book for free. You chose your title and they have quite a few to chose from there too
And on top of that you can pick up free delivery when you spend over $60(some of the travel packs are already over $60. Some are sneakily priced at $59.08) and you then get 9% cashback
Not too shabby I think
