I’m in IT, books and Google are just part of my life. I subscribe to Safari Books Online because and I use it a lot. I’ve got both a Kindle and my iOS devices and I have books across both. But one in awhile there are books that I want to own. I call/categorize these as foundational books. These are books that I want to refer to often. Then there are topical books which I refer as needed.
I was looking for a couple of “foundational” books on Amazon and found one that I wanted. So I paid the $28 dollars and was on my way. But what I really liked was at the end of the purchase, Amazon presented me with an option for getting the eBook version for $2.00. $30 bucks for the pair. Which I ended up doing so I could start reading it on the spot. Great way of promoting/marketing the physical and virtual!
