i'd agree with the sales aspect. B&N want to sell their books and if they set the price and 1 person buys them all, what do they care? It's like anything else. Whoever has the means and the opportunity comes out ahead. Sometimes it's just a matter of timing. Still, it does suck to not even have a chance to buy one. I suffered a similar fate on a Cal Ripken signed book I tried to order, so I guess buying new signed books from a bookseller is a losing battle for me.
I never did check out the Mookie link, because I have his signature. Looks like Mookie is still in stock though.
I had an ebay jack-A fail to sell me his Orr auto'd card. I had won it cheap at auction($15), probably because he was a new seller and did a poor job of listing it, and paid immediately. After about 2 weeks, I inquired about the card that had not showed up yet and he claimed he'd lost it. Then I noticed that he'd relisted it as a BIN for about 7X the price I won it for. I called him on it and he then asked me to cancel our transaction because he thought he'd get more for it and was unhappy with the final price. I briefly explained (to deaf ears) how ebay works, told him I wanted what i had rightfully won and filed a claim. Eventually got my refund and left him the much deserved feedback that he earned. Of course, he was an ass about that as well. It is really amazing the quality of human beings we have created over time.
