Within the last month Spider-Girl has once again survived a bout of the cancellation blues. It seems this time around though it seemed that no sooner was it announced than the decision was reveresed.
Basically, Spider-Girl will continue, but to ensure it's financial viability it will increase in price by a US$0.25. Marvel does warn though that this fix will not keep Spider-Girl indefinitely, unless sales increase within the year Spider-Girl may still be cancelled.
