Hoochee mama, this is what I have been waiting for!
How good a discount is it?
First Things is great at writing but not so canny that they point out you are getting a half-price subscription, so as the advertising person I will do so. Dispensing with the niceties of never using whole numbers as a retailer, essentially you are spending $20 for a $40 subscription.
Via that First Things blogger par excellence, The Anchoress where you will find the all-important discount code!
