Buying a Single Spell

You used to be able to purchase a single spell that was needed... but I don't see that option anymore. :(

They removed it in the marketplace revamp. 

WOTC and DDB quite recently cancelled a la carte type of purchases, so it's sadly not possible anymore (also they kind of started this practice with few of last books like BMT where a la carte wasn't available)

Thank God I bought Fey Touched and Circle of the Moon when I did, but I'm sad I can't have Gift of Alacrity for it without buying the whole book
