when i first got my ereader i got lots of kindle free books and converted them to epub to read on my sony. i now have a kobo and cant be bothered with the hassle of converting/removing drm. I have no trouble buying and downloading from sainsburys and kobo and any other sites apart from kindle.... have that many books that if i miss out on a good deal on kindle (with the fact it has more purchasing power than other resources they have better deals) i wont miss it till i really want it
