Hey Joe!
Become an AWS member and order your AWS D1.1 book from your local AWS section's education library instead which will give you a substantial discount compared to the $475.00 Non-member list price... For example, the Pittsburgh Section offers AWS members 40% discount on AWS publications including code books!!! :) :) :)
Now I don't know what the LA section, or whatever section you belong to offers their members, but it should be close to the same... Something to consider for sure!!! ;)
Respectfully,
Henry
