According to Bon Alimagno over at Newarama.com Vampirella comics are going to attempt selling the book for $1.99. This is an attempt to bring back readers and get the character back into the top 100. They are calling for fans to join their Myspace page and Twitter to help promote the character's 40th anniversary. They claim they might be able to do the lower price, unlike Marvel and DC, due to low overhead and smaller staffing.
While Vampirella has never been one of my all time favorite characters, I have enjoyed the book the few times I picked it up in the past. For $1.99 I'm willing to give it a try.
