Book sale Embargoes

[Slyvester Buchelem]

Does anybody else find it weird that in Accio Deathly Hallow Hank sings incendio book sales embargoes and the the book sale embargo on The Fault in Our Stars is ignored?

i think it's more just a frustrated potter fan that anything serious against book sales embargoes ;) 

also, the fault in our stars is by his brother and since when did brothers ever agree on anything... much.... well they are awesome brothers. XD
