Lonely Planet is doing a Buy 3, Pay for 2 promo on all their books this month. Plus, use coupon code: CJCOUPON10 for an extra 10% off.  Shipping is free on orders over USD $40, AUD $60, UK £25, EU 35 (Shipping is about $6 on orders less than $40 in the US).

Here’s how the deal stacks up to Amazon (my usual go-to site for cheap travel books):

Lonely Planet:
Southeast Asia on a Shoestring – $25.99
Hanoi & Halong Bay Encounter Guide – $11.99
Vietnamese Phrasebook – Free ($8.99)
Shipping: $6
Total: $43.98

Amazon:
Southeast Asia on a Shoestring – $17.15
Hanoi & Halong Bay Encounter Guide – $9.59
Vietnamese Phrasebook – $8.99
Shipping: $0 (free super saver shipping)
Total: $35.73

So, the Lonely Planet deal is only good for the country or regional guides that run about $25 (or books that you can’t find on Amazon), so you would get 3 books for about $52 (& free shipping), which is the same price as Amazon. Tough deal LP! This might be a deal for Canadians/Australians etc since Amazon.ca doesn’t list as cheap of books as Amazon.com (US) & there isn’t an Amazon.au yet.
