I would love to see the Eerdman's Wesleyan Commentary under contract. As of now it looks like it is about 75% of the way there. It is well worth the price. Why not go have a look and put in your pre-pub order? You would have plenty of time to gather funds to cover it before it ships, and if you should fail to come up with the necessary funds by time of shipment, you always have the option of canceling your order.
