$79 for the basic package? A bit pricey if you ask me.

Fair enough! IMO, it's worth it :). You could spend a bunch of time cobbling together free resources, and you'd still only get about 30% of what's in the book. How much is your time worth as a software engineer?

That said, a few notes:

1. I added a coupon code ('HACKERNEWS') to knock $20 off Basic, $30 off Plus, and $50 off Premium.

2. If you're from a country where PPP makes this pretty expensive, hit me up. I'm happy to help.

3. If you're facing income challenges due to COVID-19, hit me up, I'm happy to help.

4. If this is unaffordable for any reason, hit me up, I'm happy to help. :)

Your book does an excellent job explaining the single-table design pattern of DynamoDB. This pattern literally saves you money. So at a certain point you will earn back the $79 from a lower AWS bill (plus your applications will be much faster!)

Thanks, Matthew! Appreciate it, and I agree with you :)

If your rate is low enough that you can learn everything that is in this book for $80 worth of your time, then sure. Price is relative, it's not like he's selling prescription drugs for $1000 per pill.

I bought it and have found it to be completely worth the money. I don't look at prices for these things in relation to how much other books cost but how much time it will save me.

Yeah I think that the medical comparison is a good idea.

We tend to criticize people for asking decent amount of money in our industry whereas people on others industries shamelessly ask for ludicrous amount of money even for pretty much anything (think medical or legal)

Alex was super-helpful to me. I had an edge-case problem using batch writes; the issue was assembling the batch in R to pass through the paws api, basically a bunch of really tricky nested lists, and I had one element out of place.

Alex answered my questions in such a way that I myself saw where the bug was in my code.

He saved me easily several hours of time.

At my hourly rate, this means that the book had a negative cost in my case.

I was able to repay the favor, I suggested an improvement to one code example in the book which Alex eagerly accepted.

Thanks for your support! I'm grateful for the fix you suggested as well :)
