Borrow first.

Buy if on a decent sale and I know that I'm likely to read the book/series again. I read far too much to buy every book.

Even if ebooks only cost $5 or less, that would still be a $500-600 chunk o' change yearly. I got my first library card in 3rd grade. Libraries have always been my lifeline to affording my reading habit and this has not changed in 60 years.

Of course, sometimes I see a good sale on something, and just go for it if the book sounds interesting. Likewise if it's an author I've read before and liked their work. At least once, I had a book on a library hold from a favorite series (Laurie R King's Mary Russell mysteries), spotted a good sale on the recently released title, and snagged the ebook and cancelled my hold.

If/when I buy, where is mostly the Kobo store, but sometimes also Google Play. I accumulate Google Play points weekly, there's no reason not to use them up on a book purchase when I have enough. For the same reason, before Amazon started locking things down by disallowing downloads from my content library, I sometimes bought there using Kindle points. I've also bought from independent publisher sites, authors, and even Smashwords a couple of times. As well as some long defunct vendors.

And, I happily make use of the public domain. Free, and so much great reading. Having my second go at War and Peace currently, and enjoying it immensely. Last read it over 50 years ago in high school!

As for e-readers and ecosystems, I've mostly stayed agnostic. I started with a Nook, switched within a year to a Sony, went Kobo when Sony stopped making ereaders, but also picked up a Kindle to try it out. Mostly read on my Kobo, but I also enjoy a used Pocketbook Era I picked up on eBay for a great price. I will buy whatever device works for me and my aging eyes and my general preferences.
