Harlequin is the one publisher that gets most of my money because they do get it right on ebooks. I usually wait for a good Kobo coupon then buy the month's latest titles there at a really good price. I never buy at full price unless I want to read the book right at that moment. I have no complaints because their prices are really reasonable. They have good formatting unlike some agency books I have bought.
I also love how they are now publishing backlist titles into ebooks monthly.
They are making old titles available again which I had to previous hunt down at used bookstores or through merchants online. I wish more publishers would do that. I prefer ebooks over a used smelly spine creased paperback because most people don't take care of their books properly. Buying a used paperback books online you never know what "real" condition the book is in till it arrives. I have lost money that way. Harlequin has the right idea by offering back titles in ebook form. I know what I am getting and it's usually at a good price.
