Hellmark, sorry about the typo! Re: the price filters - that's exactly what we thought - something is better than nothing, and we will add better filtering soon.
Ahi, we definitely want to include non-English books. I've noted your link.
Timoleon, way to go!
Seventh Son, being geeks ourselves, we love the prefix idea. You might see it sooner than you expect
BearMountainBooks, thanks a lot for checking, and for your kind words. Yes, we want to start telling more people once we address some of the suggestions posted here and iron out the remaining issues. I will PM you as soon as we are ready for prime time!
Daithi - thanks. We like 1001books too.
nboshart: better sorting/filtering seems to be one of the most popular demands, so now we know what we need to work on next.
Phogg - do try it out - we would appreciate your feedback.
PennyPie - you're welcome!
peetah - I checked a few sites, and it looks like the book isn't really available in ebook format. We are thinking about making that clear in the results itself at some point. Stay tuned!
Crowl, thanks for the links - all noted. Waterstones seems to be quite popular outside the US, so it will probably go in sooner than the others.
ekaser - that's a very good point. We will probably link to the site list from somewhere in the site header itself so it's available on all the pages. Thank you.
pthwaite, thank you! We decided to start with the US since we're based here, but we're open to adding new countries (and user selections for sites they want to search). We will think through this one. The UK retailers you mentioned seem to be quite popular, so they're very high on our TODO list.
