They charge $27 per book unless you get 10 or more done in a batch, then it's $25. Included in the price is head and tail bands, a ribbon marker, ten lines of type on the spine (beyond that it's $1 per line) and two free stamps on the spine. Also, there is no upcharge for smythe sewing. If your comic can be sewn thats what they'll do. Otherwise it's DFAB. If you get a book with all of those features it is more than half the cost of getting bound at Houchen.
They told me die stamps cost $40-100 bucks to get made. Other downsides are the limited cover stock (23 colors for buckram but only four for imitation leather), three fonts and only white, gold and black stamping.
