Purely speculation but maybe its a distributor problem? I order through CGN on a regular basis and they too have seemed to slow down some. It also seems that on a weekly basis they have 2-3 books that simply don't ship from diamond. I always get everything I order, it just seems to be taking a little longer. To IST's credit the last time I placed an order with them 1 of the books was out of stock and they had to reorder. Rather then hold my entire order they (at no extra cost) sent the books they had and a week or so later sent the other book. While CGN seems to have a better back list of "out of print" titles and somewhat higher discounts on a regular basis IST seems to be a step ahead on customer service. This is not putting CGN down, I have never had a problem with them. It just seems IST is willing to take that one extra step. I stick with CGN because when putting together my order I often think of some back list book I just must have (because I am insane) and CGN is more likely to have it on hand.
