Pretty much, the industry standard for trade paperbacks is 6 issues, usually priced between 14.99 and 16.99. IDW trades of late include only 4 issues and retail for 17.99. In comparison, 4-issue trades for mini-series etc from other publishers often retail at 9.99. These are the prices before discounts online. IDW's trades actually cost more than individual 3.99 comics.
So, what's the best way to point out the obvious, that this should be discouraged? I guess posting about it and cutting back on my IDW purchases is the first thing that comes to mind for me. We don't want to end up with a worse standard.
