Alright, I've done a few searches and not come up with any threads that have previously discussed it. However, I'm quite sure it's already been done to death...
In any case, I'm now nosing about trying to find good places to buy books online for my Cybook.
I thought I'd start a list and hopefully people can add stores, with comments.
If I say "standard browsing" I mean you pick a fiction subcategory, and that's it, you get screens of books but no other way to browse.
For a quick and dirty estimate of how well stocked the store is I'm going to list how many are in what I understand is a popular genre for forum users here, Science Fiction.
Mobipocket
Shop by, as I understand it, the guys who own the format.
Standard pricing.
Standard browsing.
3276 science fiction books.
Cyber Read
Large bookstore, haven't seen much discussion of it here.
Standard pricing.
Standard browsing (although there are many more subcategories, most of these are a little unusual and sparse)
1582 science fiction books.
Fictionwise
Large bookstore. Has discounts. There's a club you pay a subscription for to get further discounts. The discounts are in the form of micropay which gives you a discount on your next purchase. Some of their books have 100% micropay rebates, which means you pay for the book as normal, and then you have free credit. E.g. you'd pay 10 dollars for a book, and then have 10 dollars of store credit left over. There are some catches I believe. They not only have standard DRMed Mobipocket books, but also ones without DRM, making for a larger selection.
Discounted pricing.
Standard browsing - Although they do seem to link book series together.
4335 science fiction books
Books On Board
Large bookstore. The discounts in this store are mainly straight discounts from the price you pay. They do also have reward dollars on selected books, which equates to store credit. Like fictionwise they also have other books to bring up the numbers.
Discounted pricing
Standard browsing
6201 science fiction books
Webscriptions (BAEN)
A non-standard bookstore. Baen is a publisher run ebookstore ( but it's begun to add other publishers). None of the titles have DRM, and is available in multiple formats.You can download multiple copies of each format.
Non-standard pricing
monthly bundles
no DRM
God knows how many books
usually the best price
