So, the price was the
same at both Amazon and the ConnStore? Just trying to make sure I understood you is all ....
Assuming that's so, it sounds like the publisher just isn't letting them offer a discount is all (obnoxious, yes, but less obnoxious that other stuff pubs do all the time

).
The fact is that, for good or ill, the pubs
do have something to say about pricing: you pay their price or you don't get their product.
For instance, the e-book of
Off Armageddon Reef (published by Tor) is $18 on Baen's
Webscriptions site when all the rest of the individual books are priced at $6 or less (I'm pretty sure, I haven't seen any others higher, anyway) -- that's the price Tor required Baen to sell it for, and I don't think there's the slightest question of
Baen's integrity on that topic.
