Due to the likelihood that Harper-Collins will withdraw from Amazon (see news item in News forum), at least for awhile, I've made purchases I put off. Will finish that this weekend since I believe the contract ends mid-month. I'm still sticking to wishlist items. At least I'm using gift card money. A month from now, they will probably have a signed contract, but I noticed while going through my wishlist items, some items that are unrelated have actually been withdrawn from the ebook market including an Andre Norton title I was supposed to get! Dang it! I've yet to see a withdrawn title come back again. I know I have 4-5 years of reading to do, but some of these withdrawn titles are part of a series and I hate to skip books.
Edited to add: Ok, I take that back. The Midsomer Murders series by Carolyn Graham in ebook came back to the US market after a 4 year absence. I noticed it back at Amazon about a month ago. That was after I gave up last Fall and bought it full-price via Kobo visiting the UK.
Ah well, Mom read it, so she was happy.
