I'm a first time with amazon, so I'm trying to figure it all out.
I checked a few authors in both UK and US store and it appears that in UK they are 1-2 pounds cheaper than in US, which is a little surprising. I thought it will be cheaper in US. Although it's in my favor that UK is cheaper. I read a lot so every pound counts
Still, I checked only a few books between UK, US and a small "original" publisher of the book (different publishers for different books) and I think it's cheaper to buy from the small publisher. Only sometimes book is cheaper in amazon. Maybe some small publishers have bigger prices, I'd need to check way more books to see the pattern.
Also, small publishers offer multiple formats, which I like. Even if I'll read on kindle, I would like to also have pdf, epub (better for calibre) versions of the book so I have a choice to read on other devices without any bother. Conversion usually gives worse result than the original formats provided by the publisher.
So at the moment it seems as I am better of buying from small publishers. That's way I wanted to hear some comments. Like, what are the advantages and disadvantages of buying/not buying books from amazon?
Do they have discounts for very unpopular, unknown books (which I read

)? I just want to know if I even need to bother with amazon book store or keep with my tiny publishers
Also I will be in UK, so if I decide to use the amazon book store it will be the UK version.
Thank you for your opinions.
